Hey CAB, I do understand what you are saying. We actually took great measures to make sure we started from scatch, new draing and did all of the dim styles, then we wblocked it out. So, that base drawing will always be in tact.
I like the above idea as well, about using design center BUT that is where you can get in trouble with using past drawings that aren't to our standards or just simply different.
Thanks again
Mark
