Windchill Workgroup Manager CGR Management
The Windchill Workgroup Manager for CATIA V5 allows you to store and reuse CGRs generated by CATIA. In order for CGRs to be correctly loaded by CATIA V5, they must adhere to a strict naming scheme which includes the timestamp of when the CATIA document was last saved. Each time a CATIA V5 document in session is saved after updating the file, a new CGR needs to be generated. This requirement can lead to CGRs being regenerated to ensure that CATIA V5 is loading the correct CGR file.
In addition to CGR files, XML documents accompany CGR files to prevent unnecessary loading of objects into the CATIA V5 session. When CAD documents are loaded into visualization mode the Windchill Workgroup Manager is unable to read the information about the document without switching it into design mode. The XML files are generated each time that the document is saved after performing an update.
