Hi guys, I hope I put this post in the right place. I am having an unending problem of design tree updates after part renames. I have been renaming a lot of parts after using a wrong part naming formate. I rename the parts in windows explorer with the solidworks explorer fuinction accessed with the right mouse button. I then rename the parts' drawings to the corresponding new name. Now here is the issue. When I go into the parts' assembly the parts are all present. There is absolutly nothing wrong with their mates, locations, or references, BUT their names in the design tree are STILL the OLD part names. However, if I open the part or its drawing the new name is associated with the document. I am working on SW 2013. I appear to be the only one having the issue in our design group. We have not been able to determine what is causing the issue. I would appreciate any help. Thanks a lot.
