The Save Modified Instances command allows you to tell Windchill that modifications have been made to individual SOLIDWORKS Configurations that have been exposed to Windchill as Family Table instances. The reason for this command is that SOLIDWORKS has no way of understanding which individual Configurations have been modified — it only knows that the file has been modified. Therefore, this mechanism enables you to tell the Windchill Workgroup Manager which Configurations have been modified, so that Windchill can correctly record changes to individual Family Table instances.

The Save Modified Instances command is only active when the Independently Modify Instances preference is set to Yes, and the active SOLIDWORKS model contains Configurations that have been exposed to Windchill; otherwise, the command will be greyed out. In SOLIDWORKS, select PTC Windchill > Save Modified Instances to access this command. See Independently Modifying Instances for more information.
