Caltrans MicroStation resources are available for download from the Caltrans Office of CADD and Engineering GIS web page. Included are seed files for all Caltrans design planes; cell libraries; custom linestyle and font resources. Click on the link "Proceed to Caltrans Resource Files Downloads". The Office of Photogrammetry will no longer provide these files to contractors.
Caltrans began accepting MicroStation V8 format files for PS&E submittals on February 1, 2008. Caltrans is also accepting MicroStation V7 format files. The Office of Photogrammetry will accept map files in either MicroStation V8 or V7 formats. All files should be based on the appropriated Caltrans design plane and resource files. Contact your District Photogrammetry Coordinator or the Office of Photogrammetry if you need assistance.
