Welcome to the Illinois Department of Transportation's CADD file
download area on the Internet. 

All CADD data files are self-extracting files.  After extracting
the executable (.exe file) you may then delete the executable file.

All updates to the cell libraries, settings manager and other
resource files will be available for download here as soon as they
become available. 

All cell libraries should be saved to your default cell directory. 

Check your MicroStation configuration to determine the proper folder
locations to place the downloaded IDOT CADD files. 

For the IDOT Settings Manager files, sm99e.stg and sm99m.stg, to
function properly will also need the IDOT macro files (.ba files)
to be downloaded.
  
Please check the IDOT website for the current version of IDOT CADD
files and/or the Departments PTB for notification of the availability of
future releases.

All technical questions relating to Internet operations should be 
left as comments to the webmaster. A representative from the Department
will check daily for questions or comments and respond promptly.
