For several years we have been creating derived parts to show machined features of castings. etc. by inserting one part into another part. I just did it again and it created a weldment in the feature tree. I also recieved a popup message telling me that the units were different from the original part. This shouldn't be possible since both were created from the same template. I just upgraded to 2014 SP3. Is this a bug?  It's a pain regardless....
