SIUE
CAD/GIS Standards
for
Facility Management and Contractors
INTRODUCTION
This information is provided to server as a guideline for SIUE (Southern Illinois University Edwardsville) users and producers of CAD/GIS (Computer Aided Design / Geographic Information Systems). All standards outlined herein is a combination of standards from governmental and professional sources, that has been modified to meet the needs of the university.
***
Drawing Size
All Drawings should conform to ANSI (American National Standards Institute) standard sheet sizes.
If possible sizes ANSI A, ANSI B, or ANSI D is preferred, This is to maintain a proper scale when drawings are converted to a deferent sheet size.

Scale and Units
-All CAD drawing models should be drafted at full scale in architectural units, such that one drawing unit equals one inch.
-For layout and plot scales use standard Imperial units, Architect and Engineering scales.
-Contractors and sub-contractors should maintain uniform scaling standard though out a project.
***
Fonts
Only fonts provided by AutoCAD are to be used for CAD drawings, third party and/or “shareable” fonts are strictly prohibited.
***
Layers
The layering standard outlined herein is a modified version Harvard University’s which or a slightly modified version of the 1997 American Institute of Architects CAD Layer Guidelines. However, please note that SIUE follows its own guidelines for naming and organizing CAD files, instead of following the 1997 AIA recommendations in these areas
