Rules for Opening a Configuration in SolidWorks and from a Workspace
Consider these rules for using Open or Open from Windchill:
If you select a generic CAD document to open, SolidWorks opens the model with the last saved configuration.
If you select an instance, and the instance is not in the workspace, then the instance and its generic CAD Document must be added to the workspace.
Unless the instance CAD document is in the workspace, the system parameters created by Windchill Workgroup Manager may not be up-to-date.
