Computer Aided Design & Drafting (CADD) Users Manual
The CADD Users Manual establishes the CADD standards using US Customary Units (English) and covers many of the resource files needed to complete a project within the Caltrans' right of way. Local agencies and consultants must also use these established standards for Caltrans projects. This manual is subject to changes that reflect Caltrans' current development/delivery process using MicroStation and Civil3D for all projects on the State Highway System (SHS).
The CADD Users Manual is only available from the Caltrans internet website and will be incrementally updated by section as needed. All previous changes to the CADD Users Manual are summarized in the CADD Users Manual Errata.
MicroStation Is the Standard Drafting Software at Caltrans
The following 2014 Caltrans Memorandum mandates the use of MicroStation as the Caltrans standard drafting software:
