I inserted two parts into a part file and used the "join" command to create a mold like feature from the other. Now when I open the file I get this message. Right click on it and this pops up. see below. When I go to "edit in context" the file that it claims that it can't rebuild is fine, no errors. How do I fix this problem? Also, the file that it is calling as the "Referenced Entity" is a file I cannot find on my computer....not even sure why it has that.
I'm running SW 2014 SP4.0
