I have an excel BOM in an exploded drawing of an assembly. 17 parts. Each time I send the drawing to my printer it adds multiple copies of the parts to the BOM. On screen right in front of my eyes. If I uncheck the update BOM feature it doesn't happen, but, if I use one of the sample BOM templates this doesn't happen. Also I made my template out of the same sample template after a little tweaking.
What little check box have I missed? What am I doing wrong?
Thanks in advance.
