Introduction
1.1 About the DESIGN Reference Manual
The PDMS DESIGN Reference Manual describes all the DESIGN commands
in detail. It also describes how the Design database is structured, the Design
database elements and their attributes.
DESIGN is normally used interactively. The Graphical User Interface (GUI)
provides discipline-based applications which help you to create, check and
report on the model. How to use the applications is described in user guides
and on-line help.
This manual is written for experienced users of PDMS DESIGN who need to
use commands; for example, to write batch macros or to customise the GUI. If
you are going to customise the GUI, you will also need to refer to the Cadcentre
Software Customisation Guide and Cadcentre Software Customisation
Reference Manual for information about PML, the Cadcentre programming
language.
1.2 Organisation of the DESIGN Reference Manual
The DESIGN Reference Manual has four parts:
•
Part 1, General Commands, describes general DESIGN commands, which
are used, for example, for setting up the display, and querying and
navigating around the Design database.
In particular, it describes how to use the command syntax graphs,
which are used to show all the options available for each command.
•
Part 2, Creating the Model, describes the commands for creating
database elements and setting their attributes.
•
Part 3 (this volume) contains details of all the elements which can be
created in the Design database, their position in the database hierarchy
and their attributes.
•
Part 4, Utilities, describes the DESIGN Utilities for data consistency
checking and clash detection, and for exporting DESIGN data to
programs such as REVIEW.

Introduction
1.3 Organisation of this Manual
Chapter 2, The DESIGN Database Hierarchy, shows all the Design database
elements arranged as a hierarchy.
Chapter 3, Introduction to Attributes, describes the different types of attributes
that Design database elements can have.
Chapter 4, Administrative and Reference Attributes, describes the Design
elements which do not have any graphical representation (Sites, Zones, etc),
and shows where they are described in the rest of the manual.
Chapters 5, 6 and 7 are the reference chapters for Equipment and Civils
Elements, Structural Elements and Piping Elements respectively.
Note:

Introduction to Attributes
All the Design attributes can be queried and set by the user. However, many
are automatically set as a result of DESIGN commands. Only the attributes
that you would normally set explicitly are described in full. The ones that are
set automatically are of interest because you can report on them.
Note that some attributes are used exclusively by PDMS modules other than
DESIGN. These are not described here.
Attributes can be divided into two categories:
1.
General attributes occur throughout the database; they are common to
most elements. For example, OWNER (every element in the Design data
has an owner), POS (position), ORI (orientation), BUILT (true or false,
indicating whether it has been constructed on site or not).
2.
Special Attributes belong to particular elements or classes of elements
and have specific meanings for those elements; for example, FLOWD
(flow direction) in a Branch.
The special attributes are either self-explanatory or are explained in the
context of the element under which they appear in this chapter. The general
attributes are best considered in terms of their effect on the Design Model, so
their meanings and applications are described in the earlier chapters.
Note:
Some special attributes are only used for drawing control within
ISODRAFT or DRAFT. How the settings of these attributes are
applied is described in the ISODRAFT or DRAFT Reference Manual.
For a comprehensive list of all PDMS attributes and pseudoattributes, see the Cadcentre Software Customisation Reference
Manual.
In addition to their standard attributes, elements may have one or more userdefined attributes (UDAs). These are set and used in the same way as
standard attributes, except that the UDA names are distinguished by being
prefixed with a colon (:) character. For further details, see the LEXICON
Reference Manual.

Version 11.3

Introduction to Attributes
3.1 Attribute Types
The following is a list of all the Design attribute types.
Name Attribute
Every element except the WORLD can be given a name. All names start with a
slash / and consist of any number of name parts separated by further slashes.
The maximum length is 51 characters. A name part consists of any string of
characters, letters, or digits, with the exception of $ or @. If the STAR
command (qv) has been used, the * character has special significance.
The names given to elements are purely for your convenience and have no
meaning in the system.
Examples:
/HX42 /HX42/NOZ1 /16/23/NH4/H21/N4 /AREA3
Real Attribute
A real attribute holds a single real number (e.g. 25.5, -0.057, 25683.5, etc.).
Real attributes are generally used to store dimensions (e.g. DIAM, XLEN, etc.).
Integer Attribute
An integer attribute holds a single integer or whole number (e.g. 1, -2, 4000,
etc.). Integer attributes are used in Piping Components to identify connection
points (ARRIV, LEAVE); in Equipment Primitives to identify obstruction levels
for clash detection (OBSTR); etc.
Reference Attribute
A reference attribute holds a reference to another element. The attribute holds
the internal system reference number, e.g. =12/106, and not the name of the
element. Reference attributes are used to forge logical links between elements.
For example, the SPREF attribute is used to link a Piping Component element
in the Design to a Specification Component in a Specification. Note that a
reference attribute may be restricted to storing the references of particular
types of element (e.g. the SPREF reference of a Piping Component may only
contain the reference to a Specification Component element, i.e. an element of
type SPCOM). The restrictions on individual reference attributes are shown in
brackets with each attribute.
Logical Attribute
A logical attribute is either TRUE or FALSE. An example of its use is the
BUILT attribute in a Pipe which is needed to indicate whether the Pipe has
been constructed on site or not.
Word Attribute
A word attribute holds a string of up to four characters. Word attributes are
used, for example, to indicate the direction of flow in a branch (FORW, BACK)
etc.

PDMS DESIGN Reference Manual
Part 3: Elements and Attributes
Version 11.3
Introduction to Attributes
Text Attribute
A text attribute holds a string of up to 120 alphanumeric characters (e.g. ’HP
STEAM’). This string must be input between closing single quotes or,
optionally, between vertical bars (useful for entering imperial units, e.g.
|4’6|).
Real Array Attribute
A real array attribute holds more than one real number. For example, the
position attribute (POS) consists of three real numbers and represents the X, Y
and Z coordinates which define the position of an element.
Integer Array Attribute
An integer array attribute holds more than one integer. For example, the
LEVEL attribute consists of two integers and is used to control the level range
of drawing detail.
Reference Array Attribute
A reference array attribute holds more than one reference to another element.
For example, a connection reference array (CRFA) is used to hold the
connection links of a four-way valve (VFWA) or a CROSS.

Administrative and Reference Elements
There are a number of elements in the Design Model whose range of
applicability is not confined to either Equipment, Piping or Civils. These
include administrative elements (e.g. WORLD, SITE, ZONE), and elements
which refer to restrictions and constraints set by the user (e.g. Penalty
Volume, Routing Plane). The elements and their attributes and Members are
explained in this section.

Ground Model Element (GRDMODEL)
Description:
Reference Element
Basic shapes and features in the site can be represented by Ground
Models. These may be natural occurrences like mounds or slopes. Each
Ground Model element is built up in exactly the same way as
POHEDRONS (polyhedrons) which are described elsewhere.
Restrictions on the form of Ground Models mean that they are of
limited use. Complex surface profiles are better approximated by a
‘dummy’ STRUCTURE containing any of the basic shapes.

Site Boundaries and Roadways Element (BOUNDARY)
Reference Element
Description:
For site layout features such as fences and roadways it will often be
sufficient to restrict modelling to lines and arcs laid out on a surface.
The BOUNDARY element allows this method of modelling by
positioning member POINTS, IPOINTS (invisible points) and
TANPOINTS (tangent points) to describe the required outlines. The
BOUNDARY can be thought of as a ‘high level’ basic element (its
identical low-level equivalent is the DRAWING, which can belong to
EQUIPMENT, STRUCTURES etc.). The BOUNDARY has the normal
drawing LEVEL attribute of a primitive, but no OBSTRUCTION (as it
is composed entirely of lines).

Equipment and Civils Elements
This section describes the elements of the Design hierarchy that are available
for modelling all non-piping (routed) items. The elements mentioned only take
on a physical appearance from the primitive shapes that they own. The
purpose of these elements is therefore to represent assemblies of primitives
that provide convenient and manageable items of plant - structures, pumps,
vessels, columns, stairways etc. In addition, they possess different Special
Attributes that can hold information relevant to their function, construction
status etc. This information can be reported on, in a chosen format, using the
standard PDMS reporting utilities.

The EQUIPMENT element represents process vessels, storage vessels,
heat exchangers, pumps and any other predefined item that is part of
the plant. The unique feature of this element is that it may own
NOZZLEs in addition to the normal primitive shapes. Pipework can be
connected to the Nozzles, thus making EQUIPMENTs intrinsic to the
process system.

Structure Element (STRUCTURE)
Description:
Main Equipment/Civils Element
The structural framework of the plant (for example, buildings, pipe
racks, equipment racks) can be modelled on a simple level using the
same basic set of primitive shapes available for Equipment (the main
difference being that such elements cannot own Nozzles).
The principal feature of the STRUCTURE element is its ability to own
SUBSTRUCTURES as well as primitive shapes, Routing Planes and
Penalty Volumes. This enables, say, a rack to be further divided into
beams and columns. (See also Section 6.1 for the use of this element in
designing Steelwork Structures.)

5.2 The Primitive Modelling Elements
This section describes the elements that give the Equipment and Civils items a
real physical shape. They comprise standard solid shapes and a special
Component of EQUIPMENT items - the NOZZLE. These elements can all be
positioned and oriented within their owning item; in order to facilitate this,
they possess standard positioning points (p-points) which also allow connection
operations.
This comprehensive set of geometric shapes forms the physical information
from which non-piping items are constructed. Each shape has a set of special
attributes that give it a physical appearance, e.g. CYLINDER has attributes
DIAMETER and HEIGHT. All the primitives contain the attributes LEVEL
and OBSTRUCTION which allow them to be selectively drawn in DESIGN or
DRAFT, or clash checked in DESIGN. (DRAWI does not have an
OBSTRUCTION as it can only contain lines).

5.3 Holes in Primitive Elements
Holes of any shape can be created in a primitive by creating a ‘negative’
primitive owned by the ‘positive’ primitive within which the hole is to appear.
Any type of positive primitive may own any type of negative primitive. The
negative shapes have position, orientation and dimensions which govern how
they penetrate their owner. Holes can pass either partially or completely
through their owners, but special rules should be observed when penetrating
the surface of a primitive.

same way as for a Negative Extrusion, but in this case the profile is
swept about an axis rather than along a linear path. The swept angle
must be in the range -360 to +360 degrees, 360 degrees giving a
volume which is axially symmetrical.

Structural Section Element (SCTN)
Description:
Structural Design Element
A SCTN represents a linear component such as a beam, column, strut
etc. It has a uniform cross-section along its length, defined by
reference to a Catalogue PROFILE element, while its length is a
derived property (not stored in an attribute) which is determined by
the Section’s start and end positions.

Generic Section Element (GENSEC)
Description:
Structural Design Element
A GENSEC can represent any component whose geometry is defined
by sweeping a 2D profile along a linear or curved path (its SPINE
element). It has a uniform cross-section along its length, defined by
reference to a Catalogue Profile element. In its simplest form, where
the Spine is defined as a line between two fixed points, the GENSEC
can be used as an alternative to the SCTN element. In its more
general form, where the Spine consists of a sequence of straight and/or
curved segments, it can represent curved beams, curved walls, etc.

Spine Element (SPINE)
Description:
Structural Design Element
A SPINE defines the path through which a cross-sectional Profile
must be swept to generate a GENSEC. The route of the Spine is
defined by a sequence of Spine Points (POINSP): one at the start, one
at the end, and one at each change of direction. Each segment linking
adjacent Spine Points can be either a straight line or an arc of a circle:
the latter is achieved by the insertion of a CURVE element (see Figure
16-24).

The Piping Elements
This section describes those elements of the Design hierarchy that allow
Piping to be modelled. These include all routed items - pipes, ducting, cable
trays and hangers. The elements described here obtain most of their physical
appearance from the PDMS Catalogue, although unique attributes such as
position are held in the Design hierarchy. The basic Components of a route are
organised into a sequence which represents its Head-to-Tail logic. It is
therefore important with these elements to control their location within the
hierarchy carefully (as achieved by the routing commands).

•
Those which are used directly from the PIPE element (by modules
such as ISODRAFT) as a collective attribute for all the BRANCHes
in the PIPE, e.g. Pipe Spec (PSPE).
Those which have no direct significance at PIPE level, but which
are cascaded downwards to member BRANCHes (or even
Components) where they perform a particular function, e.g.
TEMPERATURE - only used by Branch for insulation, stressing
etc.

Description:
When a BRANCH (or HANGER) is created, a Head and Tail are
immediately available to represent the two ends of that item. The
Head and Tail are special because they are not separate Design
elements but rather attributes of the BRANCH (or HANGER). This is
because they are always required, being the minimum information
necessary to describe a two-ended entity.
If the Head and Tail are set up with no intermediate Components, the
content of the Branch will be one piece of straight Tube (or Rod)
running between them. When the BRANCH (or HANGER) is created,
the Head and Tail have no position, orientation, bore or connection
type. These can be set collectively by connecting to another BRANCH
or a NOZZLE, or individually if positioning the BRANCH in free
space. They can also be referred to collectively as the PH and PT (or
HH and HT) respectively. The Head and Tail attributes of BRANCH
(and HANGER) are as follows:
Href,Tref
The name of the element to which the Head or Tail is connected (e.g. a
Nozzle, a Tee in another Branch, or another Branch Tail).
Hpos,Tpos
The Head or Tail position in Zone axes (PIPE has no POS attribute).
Hdir,Tdir
The Head or Tail position in Zone axes (PIPE has no ORI attribute).
Hcon,Tcon
The connection type of the item to which the Head is connected (e.g.
the flanged face of a Nozzle).

Pipe Hanger Element (HANGER)
Description:
Main Piping Element
The HANGER is a two-ended entity which is routed between a
BRANCH and supporting steelwork. It is analogous in many respects
to the BRANCH element and can own Components routed between a
Head and Tail. The Head or Tail can be connected to a piping
attachment point (ATTA) or positioned specifically, e.g. on a
supporting member. Its attributes can be classified as follows:
•
•

7.3 Piping Components
Attachment Point Element (ATTA)
Description:
Piping Component
The ATTACHMENT point has three main applications:
•
To allow pipe HANGERS to be connected to a point in the
BRANCH
• To indicate a special point on the BRANCH which can be
dimensioned, labelled, etc.
• To allow forces, moments, etc. to be applied to the BRANCH during
pipe stressing.
The ATTA is created, selected and consistency-checked in the same
way as other Components. However, it is ignored as an in-line fitting
by the CONNECT command and is ignored by the reporting utility
when listing tube lengths.
