Rules for Using Upload and Check In
Consider these rules for using Upload and Check In with SolidWorks configurations:
If one configuration is modified, when you check it in, you must check in the generic and all its instances.
New managed configurations are included on checkin.
A Design Table file is not required for checking in the generic.
