Hi all, I work in a custom sheetmetal shop, and our designer just resigned. That being said, I need to modify a part but I want to keep all assembly relations and constraints. I have done this before, but I had someone walk me thru it. now he's gone. I just don't want to have to reinvent the wheel when modifing the other assembly would be faster. the only difference between what I have and what I need is lenght, everything else is the same. Any help would be great.
