Our engineering department has just switched to version 2010. I have noticed that when I open a multi-body part it also opens all of the parts used to create that multi-body part. This has not always been the case, and as far as I know, I have not changed any settings. I have also noticed that if I open a part then save it, close and reopen the same part it opens as it should. Is this a bug or just part of the process of moving to a newer version of the software?
