The CAD Document object type is a subtype of EPM Document and, by default, the EPM Document object initialization rule autogenerates numbers.

Users may have special requirements for numbering their CAD documents depending on the workgroup manager client that they are using. For information on the numbering requirements for working with CAD documents on a workgroup manager client, see the Windchill Workgroup Manager Administrator's and User's Guide for the CAD application used by your users.
