CGR Cache Management
CGR Cache Management mode allows large assemblies to be opened more quickly and use less resources. To enable CGR cache support, select the Work with Cache System checkbox in CATIA V5 and set the cache location and size appropriately. This preference is located under > > > > .

Due to a native CATIA limitation, the path to the CGR Cache cannot be exactly 8 characters.

Assembly Handling
All candidate instances are opened to visualization mode one at a time following the read. Metadata and dependency information is cached allowing models that contain no changes to detected and not switch them into design mode. If a part does contain changes, it is opened into design mode to apply the changes.
Neutral Data Caching
Neutral cached data is used. It contains the models and metadata dependency structure. The use of cache instead of reading from the part improves the performance of the Workgroup Manager when handling larger assemblies. The neutral data is stored as an XML file and referred to as the XML data cache. The XML data cache is stored as secondary content using the primary content’s file name followed by the version of the neutral data model with a .xml extension, for example my_part.CATPart.J01.xml.
Configuration
The CGR cache configuration is done by setting the following preferences on the Windchill server. The preferences can be accessed under Preference Management at > .
