Windchill Workgroup Manager supports the use of CATIA Graphical Representations (CGR) files in assemblies. To insert a CGR file contained in Windchill into an assembly, you must add the CGR file to the workspace and then insert it into the assembly from the Workspace Local Directory (WLD).

When cache management is enabled, CATIA V5 attempts to generate and load a CGR for all CATParts present in an assembly which is loaded in-session. The CGRs are stored in a separate cache directory specified by the user. No links to these cached CGR files are stored in any documents. When the CGR is displayed in the assembly, the file it represents is in Visualization Mode and none of the data is actually loaded. If a user opens the individual part in a separate window, or switches it to design mode in the assembly, then the data is loaded and the CGR representation is unloaded.
