CAD/D
Welcome to the CAD/D Section
This area contains the documentation for the Department's Computer Aided Drafting/Design (CAD/D) system.
The CAD/D section has two primary functions: supporting and training the Department's MicroStation and OpenRoads users, and providing project visualization and photo rendering services.
Select one of the options below to view available information in that particular area.
This section contains general information and documentation that could be useful at multiple stages of the design process.
