IDOT CADD Support

Current Requirements: The Department CADD configuration is running on Window XP platform with versions of MicroStation version 08.11.07.443 and GEOPAK version 08.11.07.494. There are 760 CADD seats located in various central office bureaus and 9 district office sites throughout Illinois. Consultants should contact the appropriate District Project Manager for project related information in conjunction to using MicroStation and GEOPAK on any IDOT contract. Periodic updates will be posted on this page; we recommend you sign up for the CADD Support subscription service to be notified of updates to the CADD downloads. Please review the documents and text files included in each folder for historical details or modifications to programs and configuration files.

Future News: With the completion of the Bentley V8i product implementation, the department will focus on an IDOT Roadway Designer\Corridor Modeler in the fall of 2011. This will move the department from criteria to template based cross sections. IDOT will be moving to a Windows 7 platform for CAD desktops beginning in the fall of 2011.
