Hello All,

I am newbie to SW but was assiged to make some simple udpates to the existing SW drawings.  Hope anyone of you can provide me some help on this:

First of all, I need to change some part numbers in a exising 123.sldasm drawing.  The 123.sldasm drawing contains total 13 major components and I need to change the part numbers for 5 components.  How should I do it?  Can you direct me to some instrustion or SW user's manual?

Secondly, after the change stated above done, how do I update the BOM (shown on 123.slddrw drawing) automatically?

Thank you so much for the help in advance.

Kent
