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....
Insert part creates Weldment feature only if you choose import custom properties of the inserted part so that the inserted part properties can be stored at cut-list level without disturbing/overriding the properties of target part.
The template error message shouldn't show up if the unit information of target part and inserted part is same. I am not able to reproduce it in case both templates are same.
Can you please share the some files in which you are seeing this issue and open a SR with your reseller to report this issue..
