I have a mastermodel in SW2014 that is the first component of my assembly and it is showing a rebuild error (not a mate error). The part itself shows no rebuild errors. Querying " What's Wrong" gets me a message that a Body-Move/Copy21 uses one or more bodies that are no longer in the model. Well that's because I deleted that feature. I inherited this model and I believe that feature was a hidden one that was used as an explode step in the newer "Exploded View" feature in multibody parts. Personally I never use this feature because of this, and had deleted the exploded view.
Anybody know how to convince the assembly that my part is actually just fine?
Can you edit that hidden feature like Andrew has explained here: https://forum.solidworks.com/message/567680#comment-567680
