Hello again, I am putting together a BOM on an assembly drawing for the first time. Some of the parts just have a description and no part number. The BOM automatically puts my file name in for the part #. Is there a way just to leave that part blank? Also I would like to change some of the part numbers to match our new numbering system. Should I go change the file names or can I just change it here in the BOM and it will accept that? Thank you.
