I inserted a multi-body part into a part and I was able to move just one body, selecting THIS body well and not the whole import function. Is this the explanation? The "Body-Move/Copierx" function is located well after the insert function and not in it.
The funniest thing is that with Benoit's solution: it only duplicated the lid even if after removing the closed lid, it remains a ghost. Ghost that only appears in 3D and not in MEP!
I'm digging up this topic because I have exactly the same problem with my version of solidworks 2014 sp1... while everything was going very well under SW 2013 sp5.
Do you have a solution to propose (particular parameter to fix) or is it really a bug?
For 2 years, I haven't come back and have been satisfied with Benoit's solution.
Rereading the thread, we see that it's in the 2013-2014 transition that there is something: Benoit does his tests with SW2013 and it works correctly, with SW2014 I have the problem.
