CENTRAL MICHIGAN UNIVERSITY CAD STANDARD
1.0.0 OVERVIEW
This standard pertains to the use, production and submittal of electronic CAD information to the
Plant Engineering and Planning Office of Central Michigan University (CMU). This standard
has been developed to provide direction to consultants performing work for CMU. Prior to the
commencement of any work, Consultants shall contact the Plant Engineering and Planning
Office for the most current release of this document. This information is also available on the
Facilities Management Web page at www.fmgt.cmich.edu under Design Standards. It shall be
noted that the most efficient and effective use of CAD is not necessarily the initial generation of
the drawing file, but the capability to easily modify and reuse the file in the future. Therefore,
there shall be no restriction by the provider on the ownership of the files including the
distribution of CAD files, or parts thereof, at CMU’s discretion. By establishing and adhering to
a common set of standards, CMU can achieve significant benefits including a layering and file
naming standard based on the U.S. National CAD Standard, AIA Layer Guidelines, and the
Uniform Drawing System. It is important to note that these standards, as with any office
standards are constantly being revised and updated to keep pace with changing technology and
construction practices.
2.0.0 USER RESPONSIBILITY
Adherence to the standards and procedures contained herein is essential to preserving a
consistent and standardized character in the drawings maintained by CMU. This will increase the
efficient use of project time and management. Modifications to the standards and procedures in
this manual may be necessary for specific situations. Proposed modifications and or deviations
from this standard must be approved in writing by the CAD Manager. Do not make arbitrary
changes without prior approval. Internal change recommendations to this manual shall be
directed to the CAD Manager in writing detailing:

Why the current procedure is not adequate

What the proposed modification or addition should be

How it would improve the existing standards and procedures

Use of the CAD Standard Modification form in Appendix A is required

5.0.2.6b Sheet File Names and Numbering
Refer to the CMU Sheet Number Matrix in Appendix B.
6.0.0 DRAWING FORMATS AND GRAPHICS
Sheet borders, title block and data, Consultant’s license stamp, logos, and all other components
of the master drawing sheet shall be located in paper space. All graphic representations of the
project or facility and all related notes, dimensions, symbols, etc., shall be constructed in model
space. All graphic entities shall be comprised of representational and geometrically accurate
entities, e.g. a circle shall be represented by circle entity and not a visually equivalent collection
of line segments. Items shown in a dashed line type shall be created with the “LINETYPE”
feature and not by individual line elements.
6.0.1 AutoCAD compatibility
CAD File deliverables shall be in AutoCAD format. All files delivered to CMU shall be
thoroughly tested for compatibility and integrity. Files delivered to CMU shall be free of any
copyrighted or other material whose distribution is prohibited.
6.0.2 Entities
All graphic entities shall be comprised of representational and geometrically accurate entities.

For example: A circle shall be represented by a circle entity and not a visually
equivalent collection of line segments. Items shown in a dashed line type shall be
created with the “LINETYPE” feature and not by individual line elements. These
characteristics are typical of files that have been converted from some other
format and are not be acceptable.

Files in which all blocks are exploded or all data is on a single layer are
unacceptable. Good drawing technique goes a long way in AutoCAD drawings
and all submittals to CMU shall be of the highest quality.

The following are considered poor technique and shall not be present in CAD
products delivered to CMU. Redundant Lines - There shall be no redundant
lines. These typically are forms of multiple line segments in the same place or
two segments joined to make a single segment. This also applies to text entities.
Redundant Blocks— Care shall be taken to ensure that only one insertion occurs
for a block and that the block itself only contains one copy of the image.
Open Intersections— One of the most important and basic tools used in CAD is
object snap. By using snap, the CAD operator is sure to produce clean and closed
intersections. Intersections are very important since they provide accurate snap
positions and are required as part of area boundaries.
All entities shall be colored ‘BYLAYER’ and not individually by entity. No use
of Yellow is permitted. It may be desirable on-screen but is practically illegible
when plotted.
If the drawing is to be three dimensional than it should be consistently and
accurately drawn as such, otherwise it is a two dimensional drawing and all ‘Z’
coordinates shall be 0, 0.
All blocks shall be created from layer “0”.
Nested blocks shall be avoided.
No information shall be stored on layer “0”.
Blocks shall not be mirrored. (Mirrored blocks cannot be exploded and their
attributes cannot be edited).
Temporary blocks used during file creation or editing shall be exploded and
purged.
Both model and paper space (preferred) origins shall be 0, 0.
Drawings shall be saved with the ACAD.MNU as the current menu.
Exterior drawings shall be created with appropriate University Control Points as
their starting point.
7.0.0 DRAWING ENVIRONMENT
AutoCAD allows the choice between two drawing environments: model space and paper space.
Model space is AutoCAD’s working mode for creating the model. The model is a subset of a
building’s geometry and its physical components such as walls, doors, windows, columns,
beams, outlets, ducts, etc. The model shall always be drawn at full scale (1:1). Paper space
enables one to take the model and create a variety of views or scales for plotting. Each sheet
represents one plotted drawing at full scale.
7.0.1 Paper Space
The primary drawing shall be submitted in paper space or converted from model space to paper
space for an As-Built submission The features represented in paper space shall be scaled to fit on
the sheet. The various views of the drawings are referenced. General project graphic elements

CENTRAL MICHIGAN UNIVERSITY CAD STANDARD
such as title blocks, legends, key plans, plan titles, riser, schematic diagrams, and sheet specific
notes shall be drawn in paper space.
7.0.2 Model Space
The drawing or model shall be created in model space and drawn at full scale (1:1). Any
additional items that help define the model or add model data such as details, schedules, or
sections shall also be drawn at full scale in model space. Consistency in keeping related model
elements in model space along with proper layer assignments will allow the use of x-refs and the
ability to keep information dynamic and updated among disciplines.
7.0.3 Standard Coordinate System
All drawings utilizing a coordinate system shall correspond to the North American Datum, 1983
(NAD 83), Michigan State Plane System, South Zone in international feet, for all map and plan
view files.
7.0.4 Prototype Drawing Files
Prototype drawing files and symbols shall be utilized as provided by the CMU. These shall
include but not be limited to title sheets, formatted drawing files, drawing symbology, and other
blocks. Blocks containing attribute fields shall be filled out.
8.0.0 STANDARD SHEET SIZES AND FORMATS
All project drawing sheets shall be D size 24 x 36. Alternate sheet sizes must be approved by
CMU prior to implementation. They are as follows:

A size Plot - 8 1/2” x 11”

B size Plot- 11” x 17”

E size Plot - 30” x 42”
9.0.0 GRAPHICS
9.0.1 Text
All text shall be created only with standard AutoCAD or standard Windows TrueType fonts.
Exceptions shall be approved by the CAD Manager, and the source font files shall be included
in the root directory of all electronic submittals. All text sizes shall be plotted and displayed in
accordance with the following minimum sizes:

Schedules — 3/32”

Dimensions and Notes — 3/32”

Grid Numbers — 3/16”

Sheet Detail Title — 3/16”

Sheet Title— 3/16”

Sheet Number — 3/16’

9.0.2 Special Entity Requirements
Common symbols, doors, windows, equipment, etc. shall be inserted as blocks. Room numbers
are very important to CMU’s CAD files. They are used to provide real data throughout the
CMU. A standard block named “RMNO” Shall be used and shall contain attribute data including
not only associative data such as room number, area and perimeter, but also the entity handle of
the polyline with which it is associated. All Record Drawing submissions shall contain CMU
building room numbers, not the Construction or Consultant’s numbers. This information
shall be included in the ANNO-IDEN layer within the drawing.
9.0.3 Dimensioning
All dimensions shown in the project submittals shall be fully associative. Dimension definition
points shall be located with an appropriate Object Snap (End Point, Mid Point, etc.) or otherwise
located precisely on the project geometry. Manual input of dimension text or over-riding the
actual dimensions are not acceptable. With the following exception, CMU will allow overriding of associative dimensions in “Enlarged Detail” where building components must be
exaggerated for clarity.
9.0.4 Line types
It is recommended that only standard AutoCAD line types shall be used. If custom or compound
line types are necessary, then their definition file(s) shall have a .LIN extension and shall be
included in the root directory of the files with which they are associated and shall be included in
the root directory of any electronic submittal. Civil line types shall be a continuous line with
text. The text shall be the standard abbreviation for the utility along with the size of the utility
pipe. For example 12” Sanitary Sewer would be
12”SAN
.
9.0.5 Fill and Hatch Patterns
Vector fill patterns are acceptable but excessive use is discouraged as they make files
unnecessarily large. In many circumstances solids may be used instead of hatches. All
consultants shall be responsible for keeping files sizes within manageable limits.
9.06 Line Weights
Preliminary Recommendations:
Consultants shall be solely responsible for the production and appearance of their hard copy
submittals. Consultants shall supply line weight requirements for proper printing of
documentation by CMU personnel and shall include this information on submitted CD’s.
