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.

OpenRoads Designer is used for developing roadway layouts and 3D models of proposed projects. The links from here will inform the reader of the various components in this process.
