We have several sheet metal parts that have external references. When these external references are modified, the parts are updated and saved at the same time. On some parts, the Flat-Pattern config is not updated. I know they SolidWorks added the 'Rebuild/Save Mark' in SW 2013, is this suppose to be enabled for these configurations? I am not clear on when you should or shouldn't use this 'Rebuild/Save Mark' feature. When it comes to Flat-Patterns, I always want them updated when the Default config is updated.
