Introducing PARAGON
What Does PARAGON Do?
PARAGON enables you to generate or modify a PDMS Catalogue, with facilities for
constructing Catalogue Components under fully interactive visual control, including 3D
colour--shaded representations of the items being designed.
PARAGON combines aspects of both catalogue creation and model design functionality
within a single module. This means that a catalogue designer not only has write access to a
project’s Catalogue databases, but may also read data from the Design databases. If given
write access, the catalogue designer could also experiment with new catalogue component
configurations in a trial design database. This approach simplifies catalogue maintenance
and design. Similarly, it is often useful for a plant design engineer to have access to the
Catalogue to query details of specific components.
PARAGON has a Graphical User Interface consisting of forms and menus. The interface
provides access to the most commonly used facilities. To enter direct command syntax, use
the Display>Command Line menu option to open a special window which accepts
command inputs and displays system outputs. Full details of using PARAGON’s menus
and forms are given in the on--line help, and how to design your own graphical user interface
is explained in the Cadcentre Software Customisation Guide.

About this Manual
This document is a Reference Manual for PARAGON. It describes all of the PARAGON
keyboard--entered commands in detail. If you need information on how to use PARAGON to
carry out the principal Catalogue design activities with minimal use of the keyboard, by
using the graphical Forms and Menus interface, refer to the on--line help for the PARAGON
applications.
It is assumed that you have attended a PDMS training course and are familiar with the
basic concepts underlying the use of PDMS.

Introducing PARAGON
NOTE: The PARAGON and DESIGN modules share a common command syntax, but
differ in that PARAGON operates on a Catalogue database while DESIGN
operates on a Design database. Only the Catalogue construction commands are

Commands
This section describes the conventions used in this manual to describe commands to be
typed in from the keyboard. The description of each command follows a standard format
which is designed to allow the basic attributes of a command to be interpreted easily. To get
the best out of this manual, you are strongly urged to read this section thoroughly.
2.1.1 Command Description Format
Once you have located the required command in this manual, you will find that it is
described in a standard format. This format is described below.
D
Title (e.g. Setting Level Representation)
D
Keywords This is a list of those PARAGON command words which are the prime
constituents of the command syntax which carries out the given function.
D
Description This is a brief description of the use of the command.
D
Example(s) These are examples of typical command lines that show the effect of the
principal options. Special notes on the behaviour of the command in specific conditions
are given here.
D
Command Syntax This shows the actual command with its possible options. The
notation used for commands is described below (Section 2.1.2).
D
Querying The relevant querying options are listed.
2.1.2 Syntax Diagrams
The commands described in this manual have their legal command and interrogation
options presented in the form of syntax diagrams. These diagrams formalise the precise
command sequences which may be used and are intended to supplement the explanations
given in the appropriate sections of the manual.
VANTAGE PDMS PARAGON
Version 11.5
Reference Manual
2--1
Communicating with PARAGON
The following conventions apply to syntax diagrams:
D
All diagrams have abbreviated names. Such names are composed of lowercase letters
enclosed in angled brackets, e.g. <expres>. These short names, which are used for
cross--referencing purposes in the text and within other syntax diagrams, are
supplemented by fuller descriptions where they are not self--explanatory.
D
Commands to be input from the terminal are shown in a combination of uppercase and
lowercase letters. In general, these commands can be abbreviated; the capital letters
indicate the minimum permissible abbreviation.
NOTE: This convention does not mean that the second part of the command must be typed
in lowercase letters; commands may be entered in any combination of uppercase
and lowercase letters.
For example, the command
DEFault
may be input in any of the following forms:
DEF
DEFA
DEFAU
DEFAUL
DEFAULT
Commands shown wholly in uppercase letters cannot be abbreviated.
D
Syntax diagrams are generally read from top left to bottom right.
D
Points marked with a plus sign (+) are option junctions which allow you to input any
one of the commands to the right of the junction. Thus
>---+--- ABC -----.
|
|
|--- PQR -----|
|
|
|--- <dia> ---|
|
|
‘-------------+--->
means you may type in ABC or PQR or any command allowed by the syntax given in
diagram <dia> or just press Enter/Return to get the default option.
D
Points marked with an asterisk (*) are loop--back junctions. Command options
following these may be repeated as required. Thus
.------<------.
/

>---*--- option1 ---|
|
|
|--- option2 ---|
|

‘--- option3 ---+--->
2--2
VANTAGE PDMS PARAGON
Version 11.5

permits any combination of option1 and/or option2 and/or option3 (each separated by at
least one space) to be used. The ‘options’ may define commands, other syntax diagrams, or
command arguments). The loop--back construction may form an exception to the rule of
reading from top left to bottom right.
The simplified format
.----<-----.
/

>---*--- name ---+--->
means that you may type in a list of PDMS names, separated by at least one space.
2.1.3 Standard Command Tools
Command Tool is a generic term covering command arguments (or atoms) and command
parts. Both classes of command tool fit into ordinary commands and provide different ways
of stating a particular requirement. Command tools may be PDMS--wide or
module--specific. This section describes the standard Command Tools that may be used in
PARAGON. They may be one of the following:
D
Standard Command Tools -- which fit into ordinary commands
D
External Macro Facilities -- which can be used in a stored macro file and which control
the behaviour of the macro when it is executed
D
Standard Concepts -- which apply globally within PARAGON
Some of the main command tools (or the PARAGON variations of them) summarised for
convenience:
"
Command Arguments
Command arguments are also called atoms because they cannot be broken down any
further. They are individual units which PARAGON can recognise as constituents of a
complete command. They usually need to be separated by spaces so that they are
individually distinguishable. Command arguments are distinguished from the other
command parts by being written in lower case italics. The principal command arguments
are:
integer
a positive or negative whole number, e.g. 2 --5 25
value
a signed number with or without a decimal point, e.g. 2.5 5 --3.8
letter
a single alphabetic character
word
a sequence of up to four letters with significance to PDMS
VANTAGE PDMS PARAGON
Version 11.5
Reference Manual
2--3
Communicating with PARAGON
text
a string of alphanumeric or symbol characters, which may include spaces,
enclosed between single closing quotation marks ’...’ or |...| characters. This is
normally used to add descriptive material to an appropriate attribute. For
example, DUTY ’Low Pressure’. (Note that paired quotation marks ‘...’ will not
work.)
space
the space bar (not usually specified unless of special significance)
name
a sequence of characters preceded by a / character and representing a PDMS
Element name, e.g. /VALVE1.
filename
an external file name of the format /filename
varid
an identifier (for use with the VARIABLE command within macros) of the
format !name, where ‘name’ is a text string. For example: !COUNTER !height
comma
the , character, which can be used to concatenate PARAGON commands; for
example: NEW UNIT, BUNI INCH, DUNI FINC
plus minus
star solid
the +, --, * and / characters, which can be used within
expressions, for example: (1 + 2), (1 -- 2), (1 * 2), (1 / 2)
(Note that there must be a space before and after each of these command
arguments.)
"
Command Parts
Command parts are subsets of the general command syntax which are used frequently
within other command sequences. The following command parts are summarised here:
Expressions
Any mathematical, logical or alphabetical expression whose result replaces it in the
command syntax.
Dimensions
A physical dimension entered using default or explicit units.
Catalogue Element Types
A word used to represent a specific type of element in the Catalogue database hierarchy.
Element Identifiers
Methods for specifying which database element you want your next commend to act upon.
Cursor--picking Identifier (<sgid>)
This command part defines the most general method of identifying an Element. The
command is completed by picking an element using the cursor in a graphical view.
"
Expressions (<eval>)
If a value given within a command needs to be calculated from other known values, you can
enter an expression from which the required result is to be evaluated by PARAGON as it

identify where it begins and ends.
Full details of the expression syntax are given in the Cadcentre Software Customisation
Guide and Cadcentre Software Customisation Reference Manual, and are also available as
on-line help.
"
Dimensions (<uval>)
Once the working units have been specified, all dimensions input subsequently will be
assumed to be in those units unless you override them. (Note that these are simply specific
examples of the use of ‘real’ expressions. You can include explicit units of measurement
when entering a value in any expression.)

General PDMS Commands
The commands in this chapter are available throughout PDMS.
3.1
Entering PARAGON
Keyword:
PARAGON
Description: This command is available throughout PDMS, allowing PARAGON to be
accessed at any time.
3.2
Leaving PARAGON
At any point during a PARAGON session, you can elect to leave PARAGON and enter
another module of PDMS. This is simply a matter of inputting the name of the module to be
accessed. At this point, PARAGON will automatically save the results of the working
session and change to the new module. However, all graphical displays, forms and menus
will need to be redefined at the beginning of the next session. In order to avoid having to
redefine a view and screen layout, it is possible to save the current status of a working
session by use of the RECREATE command.
3.3
Saving and Restoring the Current Display Status
Keyword:
RECREATE INSTALL
Description: If the intention is to leave PARAGON for a short period only this facility
allows the display definition and status (including the full forms and menus
set) to be saved, for restoration later.

3.4
Saving Work and Updating Databases
Keyword:
SAVEWORK GETWORK
Description: These two commands are complementary. SAVEWORK lets you update the
databases to incorporate any changes you have made during your current
PARAGON session (since your last SAVEWORK). GETWORK lets you
refresh your view of all READ databases to pick up any changes that others
may have made since you first opened them.
Both commands can be restricted to specific databases within the current MDB by
following them with a list of numbers. These numbers represent specific databases in
the order they appear in the output of the STATUS command, which may be given in
ENTRY, MONITOR or in the MDB mode of any GUI module. If no database numbers
are given, then the commands apply to the whole MDB.
It is good practice to use SAVEWORK frequently, to ensure maximum data security.
However, it should only be necessary to use GETWORK when there are specific
changes that you wish to pick up (in which case it is likely that you will know which
databases you will actually want to refresh). GETWORK slows subsequent database
access because the information has to be re--read from disk, and should be avoided
unless you really need to use it.
GETWORK automatically updates all volume views to reflect any changes in shared
databases.

Saving the Alpha Readout to File
Keywords:
ALPHA LOG
ALPHA FILE
Description: This facility lets you save the alpha display information to a text file in the
computer operating system. Two types of output are available, depending
on the command used.
ALPHA LOG enables the contents of either or both of the COMMANDS and
REQUESTS alpha regions to be written to a file.
ALPHA FILE enables the contents of the REQUESTS region only to be written to file.
The ALPHA LOG/ ALPHA FILE facilities may be used to save data or as a general
output facility.
NOTE: After an ALPHA file has been opened, subsequent output will be directed to both
the file and the screen until the file is closed, or until you change to another PDMS
module.

Description: When a macro error occurs, there is an audible alarm at the workstation to
signal that the error has occurred. Occasionally, macro errors can be
anticipated and no audible warning is required. This command allows the
audible warning to be switched on or off either interactively or via a macro.
If the audible warning is ON, it will sound whenever an error alert is displayed.
Examples:
ALARM ON
-- Switches the audible tone on (this is the default).

Description: This command, applicable in TTY mode only, controls the automatic output
of the Current Element name and attributes. With Trace set to ON, the
attributes display is automatically updated for each element accessed.
With Trace set to OFF, the attribute display is not changed. When macros
are being run, TRACE is always set to OFF automatically.
Examples:
TRACE OFF
Stops the automatic output of attribute data.
TRACE ON
Restarts automatic output of Current Element name and
attributes.

General PDMS Commands
3.10 Defining Colours
Keywords:
COLOUR ACTIVE CE VISIBLE AIDS
Description: These commands allow colours to be defined so that the status of different
types of item in the display may be distinguished by means of colour. The
colours used have default settings, but these may be redefined.
The colours may be assigned by using the COLOUR command to define the
Red--Green--Blue mix for a colour number or to assign a predefined colour mix by
name. PARAGON allows the use of 100 user--definable colours, plus some specific
ones which are assigned to items which need to be readily distinguishable in the
display.
Definitions:
D
The Active colour is used for the catalogue component being worked on (the
significant element, e.g. ELBO, VALV). If the current element is a geometric
primitive, the active colour is used for all primitives owned by the significant element
except the current primitive.
D
The CE colour is used for the element currently being accessed (i.e. the element
highlighted in the Members list). This may be either a primitive or a significant
element.
D
The Visible colour is used for any element in the display other than those to which the
active or CE colours apply.
D
The Active and Visible elements together constitute the Draw List.
The predefined colour mixes which you may specify by name are as follows:

The Catalogue Database
This chapter details the structure of the PDMS Catalogue database.
Note that words of four or five uppercase characters which appear in this chapter (for
example, CATA, BLTA, SPREF) are PDMS element names. When an element’s member list
is queried in PDMS, each element type will be displayed as a four--character name. Five or
six characters are occasionally used in this chapter where this gives a ‘PDMS’ name which is
closer to the element’s ‘English’ name, for example SPREF (instead of SPRE) for
Specification Reference.
4.1
What is the Catalogue For?
The Catalogue in PDMS serves a purpose similar to a parts catalogue to which a pipework
designer or structure designer would refer when using ‘conventional’ design methods. It
contains details of all available components (piping and structural), including their
dimensions, geometry and drawing symbols. Whereas the conventional parts catalogue is a
book held in the Design Office, the PDMS Catalogue is a database held on the computer.
4.2
Principal Features of the Catalogue Database
If a new Catalogue database (DB) is required, PARAGON can be used to construct it -- see
Chapter 8 for details of creating and manipulating a Catalogue DB using PARAGON.
The Catalogue data is held according to a strict hierarchy which is similar in form to that of
the Design data.
When a Component is selected by the designer using DESIGN, a Specification Reference
(SPREF) is identified and held in the Design database. The SPREF points to a Specification
Component (SPCOM) in the Specification. This in turn points to a Catalogue Component
(SCOM, SPRF, SJOI, SFIT, etc.) in the Catalogue (see Figure 4--1).

may be specific to a company but general to a number of projects in that company. For
example, the same Catalogue Component may be referred to many times in a particular
design and may also appear in other design projects proceeding at the same time.
Catalogues are usually built up as a library of catalogue macros. A selection of these macros
can then be used to build up a project--specific Catalogue database containing only those
Components which might be used on that project.

Structure of the Catalogue Database
Catalogues are constructed as a hierarchy of elements. Each element has certain
attributes and some may contain further member elements. The complete Catalogue
hierarchy is shown in Figure 4--2.
Note that in any discussion of attributes which may appear in the rest of this chapter, the
‘standard’ attributes of TYPE, NAME, OWNER and LOCK will not be mentioned, as these
are common to all the elements described below.
In addition, user- defined attributes (UDAs) may be used with Catalogue database elements
-- see the VANTAGE PDMS LEXICON Reference Manual for details.

Catalogue (CATA)
CATA is the highest level element of the Catalogue hierarchy. Its attributes include:
D
DESC -- a text description of the catalogue.
D
PURP -- a PDMS word showing the specific purpose for which that catalogue is
intended. This should be set to the same word as the Specification with which it is to be
used; e.g. PIPE, FITT.
D
CSTA -- the Catalogue standard.
A CATA can contain a number of Catalogue Sections. These are of two types: Piping
Sections (SECT) and Structural Sections (STSEC). They are the principal
administrative elements by which the Catalogue is divided and arranged. The Catalogue
can also contain Text elements (TEXT) -- see Section 9.6.
All elements referred to in a Specification (see the SPECON Reference Guide) must exist
within a CATA hierarchy, although elements may exist within a CATA which are not
referred to by a Specification.
Note that the following elements may also exist within the Catalogue database at the same
level as CATA:

Catalogue Sections (SECT and STSEC) and
Categories (CATE and STCA)
Sections and Categories are administrative elements which let you segregate particular
types of catalogue data into logical parts of the hierarchy. Sections, which subdivide an
overall CATA, are obligatory; Categories, which subdivide Sections, are optional (although
their use is recommended).
There are two types of Catalogue Section: Piping Sections (SECT) and Structural
Sections (STSEC). Both have the following attributes:

D
DESC -- a textual description of the section.
D
PURP -- a PDMS word showing the specific purpose for which that section is intended.
D
GTYP -- a PDMS word showing the generic type for elements contained in the section.
This should be the same word as that used to identify the elements in DESIGN; e.g.
VALV, BEAM.
Similarly, there are two types of Category: Piping Category (CATE) and Structural
Category (STCA). Both have the following principal attributes:
D
DESC -- a textual description of the category.
D
PURP -- a PDMS word showing the specific purpose for which that category is
intended. This should be set to the same STYPE as in the Specification with which it is
to be used; e.g. GLOB, GATE etc. for a VALV.
D
GTYP -- a PDMS word showing the generic type for elements contained in the section.
D
SKEY -- a textual symbol key showing how the item is represented in isometric
drawings (see the ISODRAFT Reference Manual).
D
PTRE -- a reference to a 3D P--point Set (PTSE).
D
GMRE -- a reference to a 3D Geometry Set (GMSE).
D
DTRE -- a reference to a Data Set (DTSE).
D
CDET -- a reference to Detailing Text (DTEX).
Both types of Catalogue Section or Category contain the elements 3D P--point Set, 3D
Geometry Set, Data Set, Detailing Text and Material Text, as described in Section
4.5.1. Piping Sections/Categories may also contain Piping Components, as described in
Section 4.5.2. Structural Sections/Categories may also contain Structural Components
(Profiles, Joints and Fittings), Structural Pointsets, Negative 3D Geometry Sets
and Structural Geometry Sets, as described in Section 4.5.3.
4.5.1 Elements Used in Both Types of Catalogue Section/Category
The following elements may be used in either type of Catalogue Section or Category:
D
3D P--point Set (PTSET) (usually abbreviated to 3D Pointset) -- a definition of the
position, direction, connection type and bore of a Component’s P--points, to be used by
DESIGN, ISODRAFT, etc.
D
3D Geometry Set (GMSET) (usually abbreviated to 3D Geomset) -- a grouping of 3D
primitive elements, defining the dimensions, orientation and obstruction geometry of
each primitive. Used by DESIGN and the Drawing modules.

The Catalogue Database
D
Data Set (DTSET) (usually abbreviated to Dataset) -- a grouping of DATA elements,
holding any catalogue data not stored more specifically elsewhere and which is
required for use in DESIGN or DRAFT; e.g. the cross--sectional area of a structural
steel member calculated from its parameterised dimensions.
D
Detailing Text (DTEX) -- elements containing general descriptive text relating to a
Component. Referred to from SPCOM elements in the Specification. For further details
see Section 9.1.
D
Material Text (MTEX) -- elements containing text describing the material(s) from
which the physical Component is constructed. Referred to from SPCOM elements in the
Specification. For further details see Section 9.2.
4.5.2 Elements Used in Piping Sections/Categories
A Piping Section or Category may contain all those elements listed in Section 4.5.1 plus the
following:
D
Piping Component (COMP) -- an element defining a piece of pipework. It consists of a
list of values (known as component parameters) and references to a 3D Pointset
element and a 3D Geomset element. The Pointset and Geomset make use of the
component parameter values in defining the size, geometry and connection types of the
Piping Component.
4.5.3 Elements Used in Structural Sections/Categories
A Structural Section or Category may contain all those elements listed in Section 4.5.1 plus
the following:
D
Structural Pointset (PTSSET) -- a definition of the position and direction of a
Component’s P--lines, to be used by DESIGN.
D
Negative 3D Geometry Set (NGMSET) (usually abbreviated to Negative 3D
Geomset) -- a grouping of 3D negative primitive elements (representing holes, end
preparations etc.), defining the dimensions, orientation and obstruction geometry of
each primitive. Used by DESIGN and the Drawing modules.
D
Structural Geometry Set (GMSSET) (usually abbreviated to Structural
Geomset) -- a grouping of 2D primitive elements, defining the dimensions, orientation
and obstruction geometry of each primitive. Used by DESIGN and the Drawing
modules.
D
Profile (PROF) -- a 2D structural Component defining the cross--section of a beam,
column etc. (a Section). It consists of a list of component parameters and references to a
Structural Pointset element and a Structural Geomset element. The Pointset and
4--6

Geomset make use of the component parameter values in defining the size and
geometry of the Component. In the design process, a length is associated with a Profile
to produce a Section.
D
Joint (JOIN) -- a 3D structural Component defining a physical means of attaching one
Section to another. It consists of a list of component parameters and references to a
Structural Pointset element, a 3D Pointset element and a 3D Geomset element.
The two Pointsets and the Geomset make use of the component parameter values in
defining the size and geometry of the Component.
D
Fitting (FITT) -- a 3D structural Component defining an object which is physically
attached to a Section but is not part of the structure formed by Sections and Joints. For
example, a Fitting may be used to attach a pipe hanger to a Section. The element
consists of a list of component parameters and references to a 3D Pointset element and
a 3D Geomset element. The Pointset and Geomset make use of the component
parameter values in defining the size and geometry of the Component.
The Catalogue structure as described so far may be used in various ways, but the
recommended method of use is to place only one type of element in each Catalogue Section,
and to place different kinds of Components in different Catalogue Categories. For example,
you might place all 3D Pointsets for Piping Components in one Piping Section and all 3D
Geomsets for Piping Components in another, with separate Piping Sections for equal tees
and reducing tees. When defining Profiles, you might place Profiles for Universal Beams in
one Structural Section, Profiles for Unequal Angles in another, and so on.
4.6
Text (TEXT)
The Text is a general element that can occupy many positions in the hierarchy. It can be
used to store additional information about an owning or adjacent element. The TEXT
element should not be confused with the MTEX and DTEX elements described in Section
4.5.1. See Section 9.6 for further details.
4.7
Parameters
Parameters define the size, geometry and other characteristics of Components. They are
used in setting the attributes of the Pointsets, Geomsets and Datasets to which Component
elements refer.
All classes of Component can use component parameters, design parameters and
insulation parameters. Structural Components can also use attached and owning
design parameters. Component parameters are defined in the Catalogue; the other
classes of parameters allow characteristics to be set during the design process.
VANTAGE PDMS PARAGON
Version 11.5
Reference Manual
4--7
The Catalogue Database
4.7.1 Component Parameters
Piping Components (COMP), Profiles (PROF), Joints (JOIN) and Fittings (FITT) all have a
PARAM attribute which lists the component parameters.
Section 8.2 describes how to set up the component parameters of a Component. You may
define default values which PARAGON will use if you are working with a Component whose
component parameters have not been set up. The values are set using the MODEL
SETTINGS command. For example,
MODEL SETTINGS PARAM 1 10
defines a default value of 10 for component parameter number 1. See Section 6.4.1 for the
full syntax of how to set default values.
These default values are set up only for the current PARAGON session. They are not stored
in the Catalogue DB. You must define the component parameters of a Component before
you use it in the Design DB.
4.7.2 Insulation Parameters
A design element in the Design DB refers to a main Catalogue Component (indirectly) via
its Specification Reference (SPREF) attribute. The design element may also refer to a
second Catalogue Component which defines the insulation of the first Component, via its
Insulation Specification (ISPEC) attribute. The second Component is the Insulation
Component of the design element.
Insulation parameters (IPARAM) allow the main Component to take dimensions from the
Insulation Component. When the main Component uses IPARAM 3, for example, it picks up
the value of the PARAM 3 of the corresponding Insulation Component.
When you define a Catalogue Component using insulation parameters, its dimensions are
not completely specified in the Catalogue. So that PARAGON can give some idea of what the
Component will look like when used in a design, you can define specimen values for the
insulation parameters. These specimen values apply to all Components, unlike the
component parameters which are attributes of a particular Component. The values are set
using the MODEL SETTINGS command. For example,
MODEL SETTINGS IPARAM 3 25
defines a specimen value for insulation parameter number 3. See Section 6.4.5 for the full
syntax of how to set values for insulation parameters. The values are not stored in the
Catalogue DB; they are set up only for the current PARAGON session.
4.7.3 Structural Parameters
These allow Joint and Fitting Components to take dimensions from the Section or Sections
(beam, column, etc.) to which they are physically connected. In this way, a basic design of
4--8
VANTAGE PDMS PARAGON
Version 11.5
Reference Manual
The Catalogue Database
Joint or Fitting may be adjusted automatically in the Design DB to fit a connected Section of
any size. (Structural parameters are meaningless for Profiles.)
Structural parameters are of four types:
D
D
D
D
Attached parameters (APARAM)
Owning parameters (OPARAM)
Design attached parameters (DES APARAM)
Design owning parameters (DES OPARAM)
The types of structural parameter that a Component can use depends on whether it is a
Piping Component, Profile, Joint or Fitting. In the case of a Joint, it also depends on how the
Component is used in the Design DB.
Joints are of two types: primary and secondary. A primary Joint has an attached Section in
the Design DB; a secondary Joint has an attached Section and an owning Section. (See
the VANTAGE PDMS DESIGN Reference Manual for details of primary and secondary
Joints.) Note that primary and secondary Joints are represented by the same class of
Catalogue Component, but the settings of their attributes and the attributes of their
Pointsets and Geomsets are different.
A Fitting Component has an owning Section in the Design DB.
Components which have an attached Section (i.e. primary and secondary Joints) can use
attached parameters to define the attributes of their Pointsets and Geomsets. Attached
parameters correspond to the component parameters of the attached Section. For example,
when a Joint component uses APARAM 2, it picks up the value of the PARAM 2 of the Joint’s
attached Section.
Similarly, Components which have an owning Section (i.e. secondary Joints and Fittings)
can use owning parameters in defining the attributes of their Pointsets and Geomsets.
Owning parameters correspond to the component parameters of the owning Section. For
example, when a Joint or Fitting component uses OPARAM 5, it picks up the value of the
PARAM 5 of the component’s owning Section.
You can define specimen values for structural parameters in the same way as for insulation
parameters. For example,
MODEL SETTINGS APARAM 2 300
defines a specimen value of 300 for attached parameter number 2. See Section 5.9 for the
full syntax of how to set values for structural parameters.
4.7.4 Design DB Parameters
These allow structural Components to take dimensions from Design Parameter Arrays in
the Design DB. Each design element has a Design Parameter Array with ten values. (See
the VANTAGE PDMS DESIGN Reference Manual for further details.)
VANTAGE PDMS PARAGON
Version 11.5

The Catalogue Database
Design DB parameters are of three types:
D
D
D
Design parameters (DES PARAM)
Design attached parameters (DES APARAM, structural items only)
Design owning parameters (DES OPARAM, structural items only)
Design parameters allow any component with an SPREF to use values from the design
element which refers to it (via the SPREF). For example, the DES PARAM 4 of a Component
is the fourth value in the Design Parameter Array of the design element. Design
parameters can be used anywhere that component parameters can be used.
Design attached parameters and design owning parameters allow a Joint or Fitting
Component to use values from the design elements which represent its attached and
owning Sections. (Attached and owning sections are explained in Section 4.7.3.) For
example, the DES OPARAM 1 of a Component is the first value in the Design Parameter
Array of the design element of its owning Section. Design attached parameters can be used
anywhere that attached parameters can be used. Similarly, design owning parameters in
place of owning parameters.
You can define specimen values for Design DB parameters in the same way as for insulation
parameters. For example,
MODEL SETTINGS DES PARAM 7 9.5
defines a specimen value of 9.5 for design parameter number 7. See Section 6.4.1 for the full
syntax of how to set values for Design DB parameters.

classes of Component.

There are four classes of Catalogue Component:
D
D
D
D
Piping Component
Profile
Joint
Fitting
Their attributes are described in the following sections. These attributes (other than the
component parameters) must be set to actual values (words or references to other
elements). They cannot be defined using parameters.
A reference to an element is usually set to the name of the element, for example /PTSR3, but
it can also be set as a general identifier, for example:
PTSE 4 OF SECT 2 OF CATA /ASA-CATA
The attributes of Pointsets and Geomsets may be defined using component parameters,
design parameters and insulation parameters. Where appropriate, attributes for
structural items may also be defined using design owning parameters and design attached
parameters.
A component parameter may be a numeric value, an expression or a word. (The full syntax
for expressions is defined in the Plant Design Software Customisation Guide.) An insulation
parameter, a structural parameter or a Design DB parameter may only be a numeric value
or an expression. The values assigned to parameters and the use to which they are put, and
the number of parameters used, are arbitrary, depending only on the skill and experience of
the user. Chapter 8 contains examples of the parameterisation of typical Components.

Navigating in the Catalogue Database
Hierarchy
There are many ways in which you can explore the contents of the Catalogue database, but
they fall into three broad categories:
D
D
D
Accessing a Catalogue element whose identity or hierarchical position is known
Accessing a Catalogue element whose position in the hierarchy relative to the current
position is known
Accessing a Catalogue element by picking it from the screen
It is important to appreciate that these navigation facilities provide you with access to the
complete Catalogue and not just those items shown on the graphical display.
5.1
Accessing a Catalogue Element on the Screen
In graphical form, you can jump straight to an element which is shown in the screen display
by positioning the cursor over the element and pressing the left--hand mouse button. This
identifies the item under the cursor and makes it the current element.
Alternatively, the cursor can be used in the Members menu (or the command window) to
pick a name from the text display.
5.2
Accessing a Catalogue Element by Name
You can jump straight to a known element simply by typing its name. You would usually
name an element when you create it.
5.3
Accessing an Element by Reference Number
All elements are automatically given a reference number when created. By stating this
reference it is possible to access an unnamed element. Reference numbers are not normally
shown in PARAGON, but may be obtained by the using the Q REF command.

Navigating in the Catalogue Database Hierarchy
5.4
Going to the Previously Accessed Element
Keywords:
SAME CE
Description: SAME takes you to the element you were at before you accessed the current
element. Repeating the SAME command has the effect of moving
repeatedly between two items -- it does not move back along the list of items
accessed.
If the previously accessed element has been deleted, the SAME command
will output an error message.
CE takes you to the current element itself. (This facility may seem rather
pointless in this situation; however the CE keyword is used in many
commands as a means of identifying an element to be the object of that
command.)
Example:
ADD CE -- Add the current element to the display.
Command Syntax:
>-- CE -->
>-- SAMe -->
5.5
Ascending the Catalogue Hierarchy
Keywords:
OWNER END
Description: Moving up the hierarchy involves fewer decisions than moving downwards,
as any element can have only one Owner. Two commands (OWNER and
END) allow you to move up to the immediate parent.
END differs from OWNER by allowing you to return to a Group element
from which the current element was accessed. As the Group does not own
that element, the command OWNER would go to the element’s true Owner
and not the Group.
It is possible to ascend the hierarchy in more than one step, by inputting the
type of element you wish to access. For example, to navigate from a Piping
Component to its Section would involve two successive END commands (if
a Category exists). However the command SECT would have the effect of
scanning up the hierarchy to find the Section which owns that list, thus
saving an END command.

Navigating in the Catalogue Database Hierarchy
5.6
Accessing an Element via a Reference Pointer
Keywords:
GOTO
Description: Many elements have reference attributes whose settings point to
associated elements. The latter (referenced) elements hold data which
forms part of the definition of the original (referencing) element. For
example, the geometric definition of a catalogue component is held in a
GMSET (geometry set) element which is pointed to by the setting of the
component’s GMREF attribute (see Chapter 7).
The GOTO command allows you to navigate directly to a referenced
element by specifying the corresponding reference attribute of the current
element.
Examples:
GOTO PTREF
goes to the PTSET specified by the PTREF setting
GOTO GMREF
goes to the GMSET specified by the GMREF setting
Command Syntax:
>-- GOTO -- <refatt> -->
where <refatt> is the name of any reference attribute of the current element whose setting
points to another element.
5.7
Other Navigation Commands
Keywords:
FIRST LAST NEXT PREVIOUS MEMBER END TYPE
Description: Most of the above commands can be linked together with the OF keyword to
produce general navigation commands.
Examples:
FIRST SECT OF CATA /PIPECATA
LAST PTSE OF PREVIOUS 3 SECT
FIRST SCOM OF /CATE 5
Command Syntax:

Component Design and Representation
This chapter introduces the methods of Component design and graphical representation in
PARAGON; in particular the MODEL, MODEL SETTINGS and REPRESENTATION
commands are detailed.
6.1
Component Design
Assuming that you have opened a suitable 3D view, the interactive graphical Component
design process in PARAGON is initiated using the MODEL command.
If a new Component is to be designed, then a new catalogue element must first be specified
by a command such as
NEW SCOM /CR2--1

The command
MODEL CE
(for ‘Model Current Element’) will add the new component to the 3D view.
Only complete Components may be displayed in this way -- individual Pointsets and
Geomsets may not be, although these items will easily be distinguishable, especially on a
colour terminal. (Geomset and/or Pointset elements can be removed from the display with
the aid of the REPRESENTATION command -- see next section).
The MODEL SETTINGS command can be used to specify the Component Design Data
attributes. For example,
MODEL SETTINGS DDRADIUS 75 DDHEIGHT 200
gives the Design Data attributes DDRADIUS and DDHEIGHT values of 75mm and
200mm respectively. The DDRADIUS, DDHEIGHT and DDANGLE attributes are the

Component Design and Representation
Design parameters used in the selection process for variable Components. In PARAGON it
is possible to use these attributes as part of the Component design. For example, whereas
an attribute such as PHEIGHT would normally be defined in terms of parameters, a
command such as
PHEI DDHEIGHT
(assuming a suitable current element) would set PHEIGHT to the Design height. (In such a
case, a MODEL SETTINGS command would need to be followed by a MODEL CE command
before any change in the display would be observed.)
To produce a display of a Component with insulation, the bore, temperature and working
pressure of the Component must be known. To this end the MODEL SETTINGS command
can be used to set the BORE, TEMP and PRESSURE. This must be done before the
Insulation Specification, INSPEC, can be specified. For example,
MODEL SETTINGS TEMP 300 BORE 80
would set the temperature and bore Design Data attributes (the pressure would stay at its
default value, see below). The Insulation Spec may then be specified by a command such as
MODEL SETTINGS INSPEC /INSUL1
Assuming the drawing REPRESENTATION (see Section 6.4) is correctly set, the
Component will then be displayed with insulation shown.
All Design settings can be restored to their defaults by
MODEL SETTINGS DEFAULT
NOTE: This command also deletes all default and specimen values of parameters. It
unsets the Insulation Specification.
The default values of the Design Data attributes, and the full syntax of how to set them, are
given in Section 6.4.
QUERY MODEL SETTINGS will output the Design settings currently in use. The Design
process is turned off by
MODEL END
which also has the effect of clearing the display.

LEVEL
CLFLA
TUFLA
-- the drawing level range
-- the centreline drawing flag attribute
-- the tube drawing flag attribute
VANTAGE PDMS PARAGON
Version 11.5
Reference Manual
6--5
Component Design and Representation
LEVEL is a pair of integers. CLFLA and TUFLA are logical attributes which are set to
TRUE or FALSE (corresponding to ‘ON’ or ‘OFF’ respectively). When you first create a
P--line, CLFLA and TUFLA are both FALSE.
Control is initially on the setting of LEVEL. If the PARAGON LEVEL setting is within the
LEVEL range specified for the P--line (as its LEVEL attribute) then the P--line will be
considered for drawing, otherwise it will not be. If the level condition is satisfied, then
whether a P--line is displayed or not in PARAGON depends upon the settings of its CLFLA
and TUFLA attributes and upon the settings of the drawing options specified by the
REPRESENTATION command.
The REPRESENTATION command provides a means of effectively overriding the settings
of the P--line’s drawing attributes without changing them. An example
REPRESENTATION command is
REPRESENTATION TUBE ON CL OFF
(The word CENTRELINE may be used instead of CL.)
The drawing option settings interact with the drawing attributes of the P--lines thus: if an
‘ON’ REPRESENTATION setting matches a corresponding ‘TRUE’ attribute setting (e.g.
REPRESENTATION CL ON and CLFL TRUE) then the P--line will be drawn, otherwise it
will not be drawn.
The drawing of Geomset primitives is controlled in a similar way. The next section gives
examples of how the LEVEL, CLFLA and TUFLA attributes interact with the
REPRESENTATION settings.
6.3
Geomset Primitive Representation
Whether a Geomset primitive is displayed or not depends on the settings of its LEVEL,
CLFLA and TUFLA attributes (as for a P--line) and also on its OBST attribute. (The OBST
attribute is a number which defines the degree of obstruction for clash checking.)
If the PARAGON LEVEL setting is within the LEVEL range specified for the primitive (as
its LEVEL attribute), then the primitive will be considered for drawing, otherwise it will not
be. If the level condition is satisfied then, the primitive will be displayed if it has an OBST
value of 1 or 2 and the REPRESENTATION setting is
REPRESENTATION OBSTRUCTIONS ON
The primitive will be drawn in solid lines if OBST = 2 (hard obstruction), dashed lines if
OBST = 1 (soft obstruction0.
The control mechanisms of tube, centreline and obstruction are quite independent of each
other. So, for example, if a primitive has an OBST value of 2 and the REPRESENTATION
6--6
VANTAGE PDMS PARAGON
Version 11.5
Reference Manual
Component Design and Representation
setting is OBSTRUCTIONS ON, the primitive will be drawn whatever the values of its
CLFLA and TUFLA attributes and the REPRESENTATION TUBE and CL settings
(provided that the PARAGON LEVEL setting is within the LEVEL range of the primitive).
NOTE: Whenever you use a REPRESENTATION command, the current design
Component is redrawn. If you want to change several REPRESENTATION
settings, put them all in the same line so that the Component is only redrawn once.
For example,
REPRESENTATION TUBE ON CL OFF OBST ON PPOINTS OFF
The following example shows the Catalogue representation of a control valve, and how it
might appear in PARAGON with various combinations of TUBE, CL and OBST settings.

other primitives represent the actual geometry and dimensions of the Component.
The following illustrations show the appearance of the Component under various
REPRESENTATION settings.

This is the default REPRESENTATION setting for OBSTRUCTION, TUBE and
CENTRELINE. The attribute settings chosen for this example are ‘typical’ for a Catalogue,
and so Figure 6--7 shows the ‘normal’ appearance of the valve. Notice how the OBST OFF
setting does not affect the visibility of the obstruction dish (handwheel space) since it has

The word CAT (short for CATALOGUE) in the fifth example is optional. You can use it when
setting default values for component parameters, and when setting specimen values for
structural parameters. You may find it helpful to use the word for clarity in macros, to
distinguish between Design DB parameters and other classes of parameters.
Values for any of these classes of parameters may be set in a single command, for example:

6.4.4 Setting Level Representation
Keywords:
REPRESENTATION LEVEL
Description: This command enables individual drawing levels to be specified for the
display of catalogue elements. Every basic primitive shape has an
associated drawing level range attribute stored in the Catalogue. If the
specified drawing level coincides with this range, the 3D object will be
drawn when it is added to the Draw List.
The practical effect of this facility is that it allows you to minimise visible
detail when representing catalogue items. For instance, at level 3
steelwork may be represented as single line only, whereas at level 1 the full
detail may be visible. Level 3 may well be adequate for design purposes.
LEVEL manipulation is not instantly updated on the screen. To see the
effects of a level change, it is necessary to replace the affected item in the
Draw List by Removing and Adding it.
Examples:

and TUBE settings and show all of the primitives, regardless of the other
settings.
Setting the Representation of INSU On or Off determines whether or not
insulation is shown on primitives.
These have the effect of considering all primitives which have an
obstruction level greater than zero and all primitives which are affected by
insulation parameters. As with changes to LEVEL representation, the

Creation and manipulation of the Catalogue elements is described in Chapter 8.
7.1
3D Pointsets (PTSET)
A PTSET is a collection of P--point elements. P--points are used in the design process to
position and orientate Piping Components, and to define their connectability to each other.
P--points may also be used in PARAGON to define the position and orientation of the 3D
Geomset primitives which make up Piping Components, Joints and Fittings. (Profiles do
not use P--points.)
A P--point has a 3D position and a direction, and is identified by a number. Each PTSET
includes a special P--point, P--point zero (P0), whose position is the component origin and
whose direction is the Z axis direction of the Component. It has no other attributes. P0 is
created automatically by PARAGON; you cannot change it in any way.
The numbering of the P--points of Piping Components must follow certain conventions -- see
Appendix A for a summary of these, and the ISODRAFT Reference Manual for fuller details.
There are no special conventions for numbering the P--points of Joints and Fittings.
A P--point has a connection type attribute, which is used only when the P--point belongs
to a Piping Component. The connection type attribute can be used to specify how a Piping
Component is connected to another at the position of the P--point, for example by a butt weld
or socket weld.

Pointsets and Geomsets
A P--point has a bore attribute, which is used only when the P--point belongs to a Piping
Component. It can be used to specify the bore of the pipe at that point.
PDMS’s data consistency checks (see the VANTAGE PDMS DESIGN Reference Manual)
can be used to check that the connection type attributes of Piping Components are
compatible with the corresponding attributes of the Components to which they are
connected. The compatibility of connection types is defined in a Connection Compatibility
Table (CCTAB) -- see Section 9.3 for details.
Use of the REPRESENTATION command affects how P--points are drawn by PARAGON;
see Section 6.2 for details.

NUMB must be set as a value. PAXI must be set as a direction -- see Section 8.5.2 for details.
The other attributes may be set as values or words (as appropriate), or in terms of
parameters (which in turn are values or words). The classes of parameter which may be
used depend on the class of Component (Piping Component, Joint or Fitting) which uses the
P--point -- see Section 4.7 for details. PCON and PBOR are used for Piping Components only.
They have no meaning if the P--point is used by a Joint or Fitting. For details of PSKEY
settings, see Section 8.5.8.

Structural Pointsets (PTSSET)
A PTSSET is a collection of P--line elements (PLINE). P--lines are used in the Catalogue by
Profiles and Joints. P--lines are used in the design process to position and orientate Sections
(derived from Profiles) and Joints.
A P--line is the structural counterpart of a P--point. It is a line which runs the full length of a
Component parallel to its Z axis. Viewed in the XY plane, it appears as a point. This point is
its position. A P--line also has a direction. This is not the direction of the line itself (which

is always parallel to the Z axis of the Component), but a direction from the line in the XY
plane. The position and direction are defined in XY coordinates only. Figure 7--1 shows a
two--dimensional view and a three--dimensional view of a P--line on the top of a Section.

P--lines may be used in PARAGON to define the position and orientation of the 2D
primitives in a Structural Geomset which make up a Profile. They cannot be used to
position and orientate the 3D primitives which make up a Joint.
One of the P--lines in a Structural Pointset must be designated as the neutral axis p--line.
This is used in DESIGN for positioning and orientating the Component. (The neutral axis is
the line where there is no stress in bending, and about which the Component bends.) A
P--line is designated as the neutral axis by setting the neutral axis reference attribute
(NAREF) of the Structural Pointset to the name of the P--line.

Pointsets and Geomsets
PKEY is a word attribute which identifies the P--line. It is equivalent to the NUMB
attribute of a P--point. PLAXI is a direction, equivalent to the PAXI attribute of a P--point.
PKEY must be set as a word. PLAXI must be set as a direction -- see Section 8.6.3 for details.
PX and PY may be set as values or in terms of parameters. The classes of parameter which
may be used depend on whether the P--line is used by a Profile or by a Joint -- see Section 4.7
for details. Chapter 8 gives examples of setting these attributes.
The settings of LEVEL, CLFLA and TUFLA and the use of the REPRESENTATION
command affect whether or not the P--line is drawn by PARAGON. LEVEL is a pair of
numbers specifying a range and CLFLA and TUFLA are set to TRUE or FALSE
(corresponding to ‘on’ or ‘off ’ respectively). The way in which LEVEL, TUFLA and CLFLA
and the REPRESENTATION settings interact is discussed in Section 6.2. (The settings of
LEVEL, CLFLA and TUFLA also affect whether or not the P--line is drawn in DESIGN.)
The primitives in the Geomsets also have LEVEL, CLFLA and TUFLA attributes which
affect whether or not they are drawn in PARAGON and DESIGN.
NOTE: A P--line has its own set of axes which are used in the design process (not in
PARAGON). See the DESIGN Reference Manual for details.
7.3
3D Geomsets (GMSET)
A GMSET is a grouping of 3D primitive elements which are used to make up Piping
Components, Joints and Fittings. It specifies the dimensions, orientation and obstruction
geometry of each primitive. The Geomset defines the symbol that is drawn for a particular
Component by PARAGON (and DESIGN) and also defines the obstruction geometry of the
Component for use when checking for clashes. Each symbol is built up from a combination of

The settings of LEVEL, CLFLA and TUFLA affect whether the primitive is drawn or not by
PARAGON (or DESIGN), as they do for P--lines. See Section 7.2 for details.
OBST is a number which defines the obstruction level of the primitive for use by DESIGN’s
clash checking facility:
D
OBST = 0:
No obstruction. The primitive will not clash with anything (used for
symbols and negative volumes).
D
OBST = 1:
‘Soft’ obstruction. Used for insulation, access volumes, penalty volumes,
etc.
D
OBST = 2:
‘Hard’ obstruction. DESIGN’s clash checking facility will report hard
interference with any item having OBST 1 or 2.
The LEVEL, OBST, CLFLA and TUFLA attributes are common to all primitives. Each
primitive also has additional attributes depending on its shape; these are described in the
next section.

7.4.2 Boxing (BOXI)

Figure 7--3 BOXI Catalogue Primitive
When implied tube is drawn using BOXI elements, the Y axis of the implied BOXI is set to
the PLeave direction of the preceding component. The X axis of the BOXI is set to be
mutually orthogonal to the PLeave and the Z axis of the preceding component (which
usually corresponds to the X axis of the component). The Z axis of the BOXI is then derived
from its X and Y axes (and usually corresponds to the Z axis of the component).
A 3D Geomset may contain more than one BOXI element and corresponding P--points may
be offset in the X or Z directions.
Note for Pipework Designers: If there is no preceding component (that is, if the implied
BOXI forms the Head of a Branch), the Y axis will be set to the Parrive of the following
component (that is, the first component in the Branch). If there are no components, the
BOXI will be set to the orientation of the Zone. (Since Pipe and Branch elements have no
coordinate system, this is the lowest level in the design hierarchy from which an orientation
can be derived.)

in which each p-point identifier is preceded by ‘P’ or ‘T’, e.g. P1 P2 T3 P4. When the P--point
is preceded by P it is treated in the same way as a point element (POINT) in the Design

For example, NAPP=6 means that the volume will be removed from the item itself and the
item’s owner.
The following table shows what Attached and Owner mean for items that can referenced
NGMSEs.

Structural Geomsets (GMSSET)
A GMSSET is a grouping of 2D primitive elements used to make up structural Profiles. It
specifies the dimensions, orientation and obstruction geometry of each primitive. The
Geomset defines the symbol that is drawn for a particular Component by PARAGON (and
DESIGN) and also defines the obstruction geometry of the Component for use when clash
checking. Each symbol is built up from a combination of the following three types of
primitive:

Pointsets and Geomsets
Like the member elements of a 3D Geomset, each member element of a Structural Geomset
has LEVEL, CLFLA, TUFLA and OBST attributes.
NOTE: For correct clash detection, the maximum number of primitives with OBST set to 1
or 2 in any GMSSET is 20; the order of these in the members list is not important.
See the VANTAGE PDMS DESIGN Reference Manual for details of the best way of
setting up Component data so as to minimise processing time for clash detection.
The primitives have additional attributes as described in the next section.
7.7
Structural Geomset Primitives
The following primitive elements are used by Structural Geomsets. They all have the
standard attributes and the common attributes LEVEL, CLFLA, TUFLA and OBST. The
additional particular attributes of each element are as described below.
Note that each 2D primitive has effectively two types of positional attributes which allow its
geometry to be changed progressively as it is extruded in space to create a 3D design
element (such as a structural SCTN or GENSEC element). The P... attributes define the
geometry at the Start of an extruded section, while the D... attributes define the change in
that geometry between the Start and End of the extruded section.

These commands are those which are common to all ‘constructor’ modules of PDMS and
some are used in this chapter without further explanation. However, the element types
which the above commands operate on relate to the Catalogue database rather than the
Design database (so, for example, NEXT SITE is meaningless in PARAGON).
8.2
Creating Catalogues, Sections and Catalogue Components
Catalogues and Sections are created using the NEW command. You would normally also
specify names by which you can recognise and refer to the elements created. For example:
NEW CATA /ANSI-CATALOGUE
will create a Catalogue with the name /ANSI--CATALOGUE in the Catalogue database.
NEW SECT /FLANGES
NEW STSEC /PROFILES
will create a Piping Section with the name /FLANGES and a Structural Section with the
name /PROFILES. Similarly,
NEW CATEG /ANSI-B16.5-CLASS-300-BLIND-FLANGES
NEW STCAT /UNIVERSAL-BEAM
will create a Piping Category and a Structural Category with the names given.
A Catalogue Component is represented by one of the Component elements SCOM, SPRF,
SJOI, SFIT (see Section 4.8).
NEW SCOM
will create a Piping Component with unspecified component parameters, the values of
which may be set later.
If the Component is to be named, this can be done at the same time; for example,
NEW SFIT /EKAA2VEE
The attributes of the Component (see Section 4.8) are set simply by following the attribute
with the word, name or value(s) to be assigned to it. For example:

Reference Manual

NEW SCOM
GTYPE ELBO
PTREF /PSE1
GMREF /GSE1
PARAM 20 19.1 12.7 37.1 BWD
The above commands create a Piping Component, of generic type ELBO, which is defined by
3D Pointset /PSE1 and 3D Geomset /GSE1, and which has the five component parameters
shown. The Pointset and Geomset which are referred to by name must already exist; they
would have been created by the commands
NEW PTSET /PSE1
NEW GMSET /GSE1
All five component parameters have been given values using a single command line, but
they can be given values individually by using commands such as
PARAM[1] 20
PARAM{2] 19
...
etc.
NOTE: You can only use the PARAM[number] syntax to change the value of a parameter
which has already been set.
This facility allows component parameter definitions to be ‘edited’. (Caution: If you delete a
COMP which is referred to by a SPCO -- via the CATREF attribute of a design component -this reference will be lost.). The use of component parameters and the other classes of
parameter is discussed and illustrated in the next section.
NOTE: If you give a PARAM command with, say, four values as a single command line,
PARAGON sets the values of the first four component parameters and deletes all
the rest.
You may define default values which PARAGON will use if you are working with a
Component whose component parameters have not been set up. See Section 4.7 for details.
The attributes of a Component may be queried by a
QUERY ATTRIBUTES
command, or may be queried individually by name. Component parameters can be queried
as a set by using the command
QUERY PARAMETERS
or singly by using commands such as
QUERY PARAMETER[1]
QUERY PARAMETER[2]
etc.

Using Parameters
8.3.1
Introduction
Piping Components, Profiles and Fittings each use one type of Pointset and one type of
Geomset. Joints use both types of Pointset and one type of Geomset. The attributes of
Pointsets and Geomsets may be defined in terms of parameters, set either explicitly or as
real expressions (which may themselves incorporate the current settings of other
parameters). (The classes of parameter which may be used depend on the class of
Component -- see Section 4.7 for details.)
For example, the bore of a P--point could be defined by entering
PBORE (PARAM[1])
This means that the value assigned to the bore of the P--point is the value of the first
component parameter.
The Y dimension of a box in a 3D Geomset used by a Joint could be defined as the expression
PYLEN (APARAM[2] + 3)
This means that the Y dimension of the box is to be given a value in the design process,
taken from the Section to which the Joint is attached. The value of the Y dimension of the
box is the value of the second component parameter of the attached Profile plus 3 mm.
The use of parameters makes it possible to use the same Pointsets and Geomsets for large
numbers of catalogue items. For example, there may be families of tees, valves, I--beam
profiles etc., each family containing items which are geometrically similar. In this way, the
Catalogue size and the effort needed to prepare input data are minimised.
Examples of the parameterisation of typical Components are given later in this chapter.
The values assigned to parameters, the uses to which they are put, and the number of
parameters used, are arbitrary, depending only on the skill and experience of the user,
except in the special case of a Piping Component which represents implied tubing (GTYPE
attribute set to TUBE) and which has no Geomset. In this case, component parameter 2
must be the outside diameter. If the tube is to be insulated, insulation parameter 1 must be
twice the thickness of the insulation.
Note on the use of Insulation Parameters: Insulation parameters may be used in two
ways. They may be used in an additive manner to increase the diameter or length of a
primitive or, if there is a significant change in the geometry from the uninsulated to the
insulated form, they may be used to define a new primitive. Where there is no insulation,
the insulation parameters will be zero, yielding a primitive of zero diameter (but probably
non--zero length).

which uses the P--point -- see Section 4.7 for details.
If you do not define the axis, PAXI Y is assumed.

Defining a Distance
Distance in a PTAXI element is defined by the PDISTANCE keyword (minimum
abbreviation PDIS) followed by a value or a parameter function. For example:
PDIS 100
PDIS (PARAM[1])
sets P--point position to 100 units along defined axis
sets P--point position to (value of first component
parameter) units along defined axis
If you do not define the distance, a value of zero is assumed.
For the reducing tee shown in Figure 8--2, the position of P--point 3 could be defined by the
commands:
PAXI X
PDIS (PARAM[2])
since PARAM 2 is the dimension called ‘height’.

8.5.4
Defining an Explicit Position
Position in a PTCAR element and a PTMIX element is defined by the PX, PY and PZ
keywords, each followed by a value or a parameter function. For example:
sets P--point X coordinate to 100
sets Y coordinate to (0.5 times value of third
attached parameter) units
PZ (PARA[2] * SIN (ANGLE / 2)) sets Z coordinate to (second component
parameter times sine of half design angle) units
PX 100
PY (0.5 * APARA[3])
If you do not define a coordinate, a value of zero is assumed.
8.5.5
Defining a Direction
Direction in a PTCAR element is defined by the PTCDIRECTION keyword (minimum
abbreviation PTCDIR), followed by the direction specified in terms of the X, Y, Z axes and
rotations towards those axes. For example:
PTCDIR X45Y
PTCDIR X(ANGL / 2)Y45U
-- direction is along the X axis, rotated 45 degrees
towards the Y axis
- includes an expression for the Y component
For other examples, see Figure 8--6. Note that any one, any two, or all three of X, Y, Z may be
present in the PTCDIR command line, in any order. The rotation value may be positive,
negative or absent altogether (i.e. zero). If you do not define the direction, DIR Y is assumed.
8.5.6
Defining Connection, Bore and Number
These three attributes are common to all three types of P--point elements, and are set by the
PBORE, PCONNECTION and NUMBER (minimum abbreviations PBOR, PCON, NUM)
commands respectively. PBOR and PCON may be set as parameter functions as well as as
words. Examples:
PBORE (0.5 * PARAM[2])
PCONN BWD
PCONN (PARAM[7])
NUMBER 3
If you do not define the bore or the P--point number, a value of zero is assumed.
8.5.7
Controlling the Appearance
How a P--point is drawn depends on the REPRESENTATION settings. This is discussed in
Section 6.2.

8.5.8
Specifying Pipe End Conditions for use by ISODRAFT
The symbol used by ISODRAFT to represent a particular piping component on an isometric
drawing is determined by the symbol key (SKEY attribute setting) for that component.
(See the VANTAGE PDMS ISODRAFT Reference Manual for a full explanation of this
concept.)
By default, each SKEY has associated with it a standard end condition (showing the pipe
connection type) which applies to each of the component’s connection points. The end
condition for any individual connection point may be modified, if required, by setting the
PSKEY attribute of the corresponding P--point to a PDMS word chosen from the following:
BW
CP
FL
SC
SW
PL
Butt Weld
Compression
Flange
Screwed
Socket Weld
Plain
The effect of setting PSKEY to one of these words for a P--point of type PTAXI, PTCAR or
PTMIX is that ISODRAFT will then add the symbolic representation of the specified end
condition to the symbol derived from the corresponding SKEY when it plots an isometric
drawing showing the component. The default setting for PSKEY is always NULL, which
means that ISODRAFT plots only the standard end conditions for the symbol.
Note that the effect is additive, so that ISODRAFT superimposes any user--specified end
condition (derived from a non--Null PSKEY setting) on top of any end condition which forms
part of the standard symbol associated with the SKEY. The use of the PSKEY facility is,
therefore, applicable mainly to components which do not have other end conditions already
defined, particularly those associated with user--defined symbols (as detailed in the
ISODRAFT Reference Manual).
8.6
Constructing Structural Pointsets
A Structural Pointset defines the connection information of a Profile or Joint as explained in
Section 7.2. A Structural Pointset has a neutral axis reference attribute in addition to
the standard attributes, and contains P--lines.

Notice how all the P--line attributes may be defined on one line. Reference information
concerning the setting up of the P--line attributes is given in Sections 8.6.3 to 8.6.6.
8.6.2
The Neutral Axis Reference
The neutral axis reference identifies a P--line in the Structural Pointset. It is set by the
NAREF command. The attribute is usually set to the name of the P--line, but may be set to
the P--line’s number in the member list of the Pointset. For example:
NAREF /UB-NA
/UB--NA
NAREF 3
Sets neutral axis reference to the P--line called
Sets neutral axis reference to the third P--line of the
Structural Pointset
If you do not set NAREF, DESIGN will make an assumption about where the neutral axis is.
You are strongly recommended to set the neutral axis reference in the Catalogue.
DESIGN will use as the neutral axis the first P--line in the Structural Pointset which has a
PKEY value of NA, if any. Failing that, it will choose the first P--line with a PKEY value of
NAXI, and failing that, it will choose the first P--line with a PKEY value of ZAXI. If there are
no P--lines with a PKEY value of NA or NAXI or ZAXI, DESIGN will assume that the
neutral axis of the Component lies at the component origin and has a direction along the
positive Y axis.

Defining a Key
A P--line is identified by its key in the same way as a P--point is identified by its number. The
key is defined by the PKEY keyword followed by a word. For example:
PKEY TOS
sets P- line key to TOS
PKEY may be set to any desired word value. Typical values are:
TOS
BOS
NA, NAXI or ZAXI

Top of steel, for a P--line at the top of the Profile
Bottom of steel, for a P--line at the bottom of
the Profile

Controlling the Appearance
Whether a P--line is drawn or not depends on the settings of its LEVEL, TUFLA and CLFLA
attributes, and the REPRESENTATION settings. How a P--line is drawn also depends on
the REPRESENTATION settings. SeeSection 6.2 for details.
8.7
Constructing 3D Geomsets
A 3D Geomset is a grouping of the primitive elements which make up a Piping Component,
Joint or Fitting. It specifies the dimensions, orientation and obstruction geometry of each
primitive. The Geomset defines what is drawn for a particular Component by PARAGON
(and other PDMS modules), and also defines the obstruction geometry of the Component for
use when clash checking. Each Component is built up from a combination of
three--dimensional primitives, as listed in Section 7.3.
Creating a Geomset consists of creating the relevant member primitives and setting the
attributes for each primitive. For each primitive the OBST attribute must be set, whilst for
a primitive that is required to be drawn the LEVEL, TUFLA and CLFLA attributes must
also be set. (See Chapter 6 and the DESIGN Reference Manual for details of these
attributes.) 3D Geomset elements and their attributes are listed in Section 7.4.
NOTE: Only the first 20 primitives in a Geomset with OBST values of 1 or 2 are considered
by DESIGN’s clash checking facility.
By using the TUFLA and CLFLA flags, you can create two different drawings of a
Component, a double--line representation (tube) and a single--line ‘stick’ representation
(centreline).

obstruction geometry of the Component. The Profile is built up from a combination of
Structural Rectangles (SREC) and Structural Annuli (SANN), as described in Section 7.6.
Structural Geomset elements and their attributes are listed in Section 7.7.
To define the tube representation for the Profile shown in Figure 8--3, the commands shown

Axial Attributes
Axial attributes of both 3D and 2D primitives define a position and a direction. An axial
attribute of a 3D primitive may be specified as a direction in one, two or three dimensions or
as a P--point. Similarly, the axial attribute of a 2D primitive may be specified as a direction
in one or two dimensions or as a P--line.
If an axial attribute of a 3D primitive is specified as a P--point, the direction of the axis is
taken to be the direction of the P--point, and the origin of the axis to be the position of the
P--point. If the axial attribute is specified as a direction, the origin of the axis is taken to be
the component origin, i.e. the position of P--point 0.
Examples:
PAAX -P2
sets PAAX to be opposite the direction of P--point 2 with its origin
at the position of the P--point

Detailing Text
Detailing Text (SDTE) elements contain descriptive text relating to a Component, which is
used during the construction of drawings, reports, take--off sheets etc. An SDTE element
exists at the same level in the Catalogue database hierarchy as a Component element (i.e. it
is a member of a Section or Category) and is referred to from SPCOM elements in the
Specification.
An SDTE element (which will usually be named) is created simply by typin, for example:
NEW SDTE /C/T1
The text itself exists as an attribute of the SDTE element; namely one of the attributes
RTEX, STEX or TTEX. The text is input simply by typing the attribute name followed by
the text itself in quotes; for example:
STEX ’21DD-JJOOA2 12.31’
The choice of attribute name depends on the PDMS module which is to use the related text.
STEX and TTEX are used primarily by the detailing interface modules, and the attribute to
be used will be specified from that module. The format of the text depends on the detailing
module in use -- see the appropriate Reference Guide for details.
RTEX is used by ISODRAFT, which also uses another SDTE attribute, SKEY. SKEY is a
four--character code which represents a geometric description of the associated Component
type. RTEX and SKEY must be set in order for ISODRAFT to work correctly. A typical pair
of commands would be:
RTEX ’COUPLING - SOCKET WELD 3000LB’

Connection Compatibility Tables
The Connection Compatibility Table (element name CCTA) holds a list of all the compatible
connection types for Piping Components in a set project. A CCTA is an administrative
element which exists at the same level as CATA in the hierarchy. A CCTA has Connection
Compatibility (COCO) elements as its members, each of which has a pair of coded
connection types stored as its CTYPE attribute. These connection types are those referred
to in the PCON attribute of a Piping Component’s P--points.
The commands below give an example of the setting up of a typical connection table.

Note that ISODRAFT uses the connection codes to derive bolting requirements, and so the
connection codes used must conform to certain standards -- see Appendix B and the
ISODRAFT Reference Guide for details. Setting up the Connection Compatibility Table
should be one of the first tasks to be carried out when commencing a design project using
PDMS.

Bolting Tables
The Bolt Table hierarchy contains information describing the nature of the bolted
connections of Piping Components in a project. Although the Bolt Table is part of the
Catalogue database, and so must be set up using PARAGON, it has been designed for the
exclusive use of ISODRAFT and so is described in detail in the ISODRAFT Reference Guide;
only a summary is presented here. Element creation and attribute setting is done in the

Unit Types
PARAGON enables unit types to be set up which will then be linked to relevant attributes of
the various elements which appear throughout the PDMS databases. The most common
units (the default units) are millimetres, inches or feet and inches, which are usually
assigned to bore and distance attributes. These units currently apply to all PDMS modules
except PROPCON.
You may also define other units with conversion factors to relate one set of units to another;
unit definitions can be collected together into sets to be used for different purposes.
Information controlling units is held in a UNIT element of the Catalogue Database. The
UNITS hierarchy is shown below:
WORLD
CCTA
CATA
UNIT
SPWL
MSET
USEC
MTYP
UDEF
BLTA
ATLI
The elements of the UNITS hierarchy are as follows:
D
UNIT -- The UNIT element is the top--level element of the hierarchy. It has three
special attributes: BUNI, DUNI and DFUN. BUNI and DUNI can be set to determine
the default Bore and Distance units, respectively. They are set to any of MM, INCH,
MIL or FINC (for feet and inches). A typical sequence of setup commands would be:
NEW UNIT
BUNI INCH
DUNI FINC
This would mean that, by default, all bore values are interpreted as inches and all distance
values, e.g. HEIGHT, DISTANCE, as feet and inches. If user--defined units are to be used,
9--4
VANTAGE PDMS PARAGON
Version 11.5
Reference Manual
Other Uses of PARAGON
then an MSET element should be named in the DFUN attribute of the UNIT, indicating
that that MSET element should be used as the default measurement set. Each PDMS
module has its default units initialised at run time to those defined in the first UNIT
element of the first Catalogue DB in the MDB being used. BUNI and DUNI may also be set
to NULL.
D
MSET -- Measurement Set. This element is used to form a collection of MTYP
(measurement type) elements. It is the MSET which is named in the DFUN attribute of
the UNIT element to indicate which collection of units are to be used. In practice MSET
may relate to say ‘S.I.’ or ‘IMPERIAL’.
D
MTYP -- Measurement Type. This element forms the link between a collection of
attributes and the Units Definition (UDEF) to be used for them. The attributes are
accessed via the ATLI (Attribute List) elements owned by the MTYP and the Units
Definition via its UREF attribute. The latter simply contains the name of the UDEF
element which is to be used for the attributes named in the member ATLI elements.
D
ATLI -- Attribute List. Each ATLI element contains (as its ATNA attribute) the name
of the attribute for which the UREF (see above) applies.
D
USEC -- Unit Section. This is an administrative element used to collect together UDEF
elements.
D
UDEF -- Units Definition. One UDEF is required for each non--PDMS unit that you
wish to implement. UDEF has the following special attributes:
S
ABREV -- Abbreviation. This is the abbreviation used when outputting a value under the
control of this UDEF, or when inputting a value which is in a UNIT that is not the one for that
attribute in the current MSET. The attribute is an eight--character text.
S
MULT -- Multiplier. This is a conversion factor which is used in conjunction with ADEN, to
convert from input/output units to PDMS stored units. This is done on the basis that:
Output value =
Stored value =
(Stored value -- ADEN) / MULT
(Input value * MULT) + ADEN
The exponential facility is useful in the accurate setting of MULT and ADEN. For
example:
MULT 0.12345 EX -8
will set MULT to 0.0000000012345
S
ADEN -- see MULT above.
S
SIGF and DECP -- Significant Figures and Decimal Places. These relate to the output of units.
To summarise, the unit is defined as:
(input_value * MULT ) + ADEN
and is output to SIG significant figures with DEC decimal places and suffixed by the
notation ABREV ( e.g. ‘psi’).

Use of Units
In certain PDMS modules, e.g. PROPCON, the choice of units to be used can be indicated by
using the command:
UNITS name
where name is the name of an MSET. If this is not done, the units will be those given by the
DFUN attribute of the UNIT element, as explained above.
Following this, whenever the value of a special attribute is set or queried, its name (e.g.
TEMP for temperature) will be compared with the ATNA attributes of all ATLIs under the
current MSET. If a match is found, then the UREF of the MTYP owning the matching ATLI
will be used to access the relevant UDEF.
When output, such values are followed by their abbreviations to remind you which units are
being used.
If you wish to input a value which is in a UDEF that is not referred to from the current
MSET, then you may use the abbreviation of that value as a key. For instance, in
PROPCON, if the current temperature unit is centigrade, but there is a UDEF defining
Fahrenheit (with abbreviation ‘deg. F’), it would appear as
TEMP 35 ’deg. F’
As an example, if you require a PROPCON attribute ACBO (Actual Bore) to be output in
inches, then the following syntax would be required:
NEW USEC
NEW UDEF /INCH
ABREV ’IN’
MULT 0.254 EX 2

If ACBO is referred to in PROPCON, the attribute name (ATNA) is searched for in the UNIT
hierarchy. The search then moves up the hierarchy to find the MTYP attribute UREF. The
MULT attribute of the UDEF (found from the UREF) is then applied to the stored ACBO
attribute and the ABREV is output with the resulting value.
As a further example, to define and use a unit system called /IMPERIAL, for which
temperatures (TEMP, PTEM and RTEM) will be in Fahrenheit and pressures (PRES,
RPRE and IPRE) will be in PSI, the instruction sequence would be:
NEW UNIT /EXAMPLE-OF-UNITS

Datasets
A Dataset (DTSE) is a collection of DATA elements. These can be used to store any items of
catalogue data which need to be queried directly from within the DESIGN or DRAFT
modules and which are not accessible by other means.
10.1 Attributes of DATA Elements
Each DATA element has the following special attributes:
DKEY
Data Key. A PDMS word which allows a specific DATA element to be referenced
from within DESIGN or DRAFT using the Q PROP dkey command.
PTYP
Property Type.
DTIT
Data Title. A text string describing the property stored in the DATA.
PPRO
Property. Any expression which defines a property of the item with which the
dataset is associated.
DPRO
Default Property Value. The value to be used if the true setting of the Property
cannot be evaluated at any time. See Section 10.3.1.
PURP
Purpose. A PDMS word showing the purpose for which the stored property is
relevant. For example, PARA (for catalogue parameters), DESP (for design
parameters), DATA (for general properties).
NUMB
Number. An integer which may be set to further categorise the specific property
stored in the DATA. For example, the identifying number of a PARAM or
DESPARAM.
PUNI
Property Units. The units used when evaluating the Property value.
RUSE
Real Property Flag. See Section 10.3.
The PPRO attribute is evaluated in response to the Q PROP . . . command in DESIGN or
DRAFT. The parameters in the expression may not be defined until the item is added to the
model. It can include any attributes which are valid for the design element, including
user--defined attributes; for example:
((:COST OF OWNER) * :LENGT).
The PPRO attribute can also be set to a parameterised expression which will be used in the
definition of Pointsets and Geomsets. See Section 10.3.

If the dataset associated with the component contains a DATA element with the Datakey
DBOR, and DBOR has its PPRO attribute set to the expression ( PARAM[1] + 20 ), PBORE
can be defined as:
PBORE ( RPROP DBOR )
Pointset and Geomsets with attributes defined in terms of RPROPs will have their RFLG
flag set to 1. Only elements with RFLG set to 1 need to be pre--evaluated when the item is
added to a model.
DATA elements have an attribute RUSE. If this attribute is set, the PROP attribute (or
default Property DPRO, see Section 10.3.1) cannot be set to a text expression or to an
expression containing the OF notation. RUSE is set (=1) and unset (=0) using the
commands:
SETRuse
UNSETRuse
DATA elements with PROP attributes property which can be used as RPROPs should have
their RUSE flags set. Only elements with RUSE set to 1 need to be pre--evaluated.
10.3.1
Default Values
The DATA element attribute DPRO can be used to store a default property value. When a
Design element is added to the model, the associated dataset is pre--evaluated and the
default value used if the PPRO attribute in the Dataset unset or cannot be evaluated.
The default property value can be queried from DESIGN using the pseudo--attribute
PRDE.
10.3.2
Querying
The value of RPROP can be queried using the command:
Q RPROP datakey
This command will return the result ‘RPROP unset’ if the corresponding PPRO attribute
contains a text string rather than a real value.

Checking Catalogue Database Consistency
To avoid having to transfer component design or specification errors from the Catalogue
database to the Design database before data inconsistencies can be detected, a facility is
provided for checking the main settings of a piping catalogue as you build it in PARAGON.
(This facility is not yet available for checking a structural catalogue.)
11.1 Initiating a Standard Data Consistency Check
The basic command to initiate a database consistency check, using default settings, is
CHECK <gid>
where <gid>, the element below which checks are to be carried out, may be any SPEC,
SELE, SPCO or COMP.
If you start the check from within a specification (SPEC, SELE or SPCO), all components
referenced via the starting element will be checked. If you start the check at component
level (COMP), only that component and elements below it will be checked.
(See Section 11.3 for details of the ways in which you can modify the default checking
procedures.)
11.2 What the Checking Facility Does
The following tests may be carried out:
At SPEC level:
D
D
D
Check that no question in the specification is repeated.
Check that one question in the specification is TYPE.
From the TYPE reference, check that the GTYPE of the COMP has the same setting.

Checking Catalogue Database Consistency
D
D
From the TYPE reference, check that the SKEY setting of SDTE is correct.
From the TYPE reference, check that the point set has the correct geometry, as
required by ISODRAFT.
At SPCO level:
D
Check that all of the following reference attributes are set: CATREF, DETAIL, MATX,
CMPR, BLTREF. (The BLTREF need be set only if the connection type begins with F or
L.)
At COMP or equivalent level:
D
D
D
D
D
Check that there is a valid PTREF and GMREF.
At a PTSE, check that P--points are set and that there are no duplicate numbers.
At a GMSE, check that there are primitives set and that they are not degenerate. Check
also that no invalid P--point numbers or parameters are used. Note that this test uses
catalogue parameters, so that if a primitive is constructed only from design and
insulation parameters, spurious warnings will be generated.
Check that each P--point connection type exists in the COCO tables. P--points used for
construction purposes can have connections of 0.0, NUL or NULL. The connection type
will not be checked for validity for a specific type of component.
Check that a P--point bore is valid for a recognised set of nominal bores. P--points used
for construction purposes, and a P--point with connection type CLOS, can have a zero
bore.
11.3 Controlling the Detailed Checking Procedure
You can modify the effect of the CHECK command by using additional syntax so that you
can check different types of catalogue without generating unnecessary errors.
The command options are as follows:
TOLerance CATAlogue CMPRef ON/OFF
switches Component Reference checking on or off for all component types in a SPCO.
TOLerance CATAlogue CMPRef word ON/OFF
switches Component Reference checking on or off for the specified component type in a
SPCO.
TOLerance CATAlogue GMREf ON/OFF
switches Geomset Reference checking on or off for all component types.
TOLerance CATAlogue GMREf word ON/OFF

P--point Conventions for Piping Components
You must use the following conventions for numbering the P--points of Piping Components
so that ISODRAFT can recognise them:
D
For tube components, there must only be one P--point, P1, which defines the bore and
connection type of both ends of the piece of tube.
D
For nozzles, the connection P--point (i.e. the P--point for connection to the head or tail
branch) must be P1.
D
For two--way components, the arrive and leave P--points must be numbered P1 and
P2 (in either order). For two--way valves, the spindle direction must be indicated by
P3.
D
For three--way components, the offline leg must be indicated by P3. The spindle
direction for three--way valves must be specified by using a P--point greater than P3,
which must have its bore unset.
D
For four--way components, the two straight--through flows must have P--points
P1/P2 and P3/P4. The spindle direction for four--way valves must be specified by
using a P--point greater than P4, which must have its bore unset.
D
For eccentric reducers without a connection point, the flat side must be
indicated by P3. Eccentric reducers with a connection point must use P3, with a
valid bore set, to indicate the connection point and must use P9, with bore unset, for
orientation of the flat side.
D
For U--bends, the P--points must be set as shown in Figure A--1.

Setting Up a Catalogue
B.1
Naming Conventions
It is important that certain items in the Catalogue database are named as they are
referenced from other databases as well as internally. It would be impracticable to allow
system--generated database reference numbers to be referenced as this would lead to
meaningless output from reports and isometrics.
Figure B--1 shows the relationship between the Design, Specification, and Catalogue
databases. Consistency when naming items is important, making cross--database
connections as easily identifiable as possible.
In ISODRAFT, bolt lengths for Piping Components are derived by referring to the SBOL
name. Item detail is picked up from the RTEX attribute of the DTEX and the material is
picked up from the XTEX attribute of the MTEX.
Note that the item code name on an isometric is obtained from the second part of the SPREF
attribute of a Component, i.e. its name in the Specification. In the example in Figure B--1,
the name would be output as FLANWN300100. See the ISODRAFT Reference Manual for
further details.
B.2
Example Connection Type Codes
Naming of the P--point PCON attribute of a Piping Component requires early
consideration. The PCON name is for use mainly in data consistency checking, but also by
ISODRAFT for working out bolting details. The rules for ISODRAFT are as follows:
D
D
D
The first letter of the PCON attribute of a flange must be ‘F’ or ‘L’ (the latter for lap
joints)
The first letter of the PCON attribute of a gasket must be ‘G’
The first letter of the PCON attribute of a wafer fitting must be ‘W’

The Connection Compatibility Table
The table in the previous section can be used to construct a PDMS Connection
Compatibility Table (CCTA) which sets out all the permissible connection pairs.
If an attempt is made to connect two pipework components in DESIGN, then a check is
made to see if the p--leave PCON attribute of the first component and the p--arrive PCON
attribute of the second component appear as a matching pair in the connection table. If
there is such a matching pair then the components are connected, otherwise a similar check
is made on the p--leave PCON attributes of each component. If a matching pair is now found,
the second component is ‘flipped’ and connected to the first. If no matching pair is found then
an ‘incompatible connection type’ error message is output and the second component is left
in its original position and orientation.
The following sample connection table uses the connection list given in the previous section:
NEW CCTAB
NEW COCO /FGDGGD
CTYPE FGD GGD
NEW COCO /TUBBWD
CTYPE TUB BWD
NEW COCO /GGDWGD
CTYPE GGD WGD
NEW COCO /TUBSWF
CTYPE TUB SWF
NEW COCO /SCMSWF
CTYPE SCM SWF
NEW COCO /SCFTUB
CTYPE SCF TUB
The COCO (Connection Compatibility) elements are named so that the allowable
connections are easily queried.
The above table shows, for example, that tube can be connected to a screwed female
connection but not to a screwed male connection.
Different ratings of flanges and gaskets should have different connection attributes to
ensure that different pressure fittings cannot be connected without a warning message
being issued. This principle also applies to different flange face characteristics, e.g. flat face
and raised face: however, there are some exceptions. On some jobs a flat--faced flange on a
piece of equipment may be butted up to a raised--face flange. If this is a common occurrence,
it may be worth inputting a new COCO to allow the connection.

Construction of Typical Piping Components
This Appendix gives sample macros for the construction of typical Catalogue Piping Components using
PARAGON.
Each macro starts at CATEGORY level. The view parameters used to produce the drawings shown vary
between each example, and so are not given here. Each drawing has REPRESENTATION settings of
TUBE ON CENTRELINE ON PPOINTS ON NUMBERS ON. Some of the Components are too large to
fit onto a typical view area when drawn at the default SCALE value of 1. Values of 0.5 are suggested for
examples 1 and 3, and 0.05 for example 6.
The definition for each Component includes the possibility of insulation being present, although this is
not drawn. Note how the clash geometry and component geometry have been combined.

Summary of Element Types
This appendix contains a glossary of the element types which you can use in PARAGON,
and a list of them grouped according to their function. Some element types can be created
and deleted in PARAGON, and have their standard attributes of NAME and LOCK
changed, but must have their particular attributes set by other PDMS modules. These are
indicated by references to the appropriate manuals.
The list of element types is the list of ‘special nouns’ for PARAGON (its <snoun> syntax
diagram).
