I seem to be having a problem creating a new weldment profile. I start a new part. sketch on the top plane the new profile of the tube I need (2x2x.095 square), then save it as a Lib Feature Part into the proper folder in my weldments profile directory. When I try to use it SW tells me it's a empty profile. I can open it back up in SW and the sketch is still there. I haven't created a new weldment profile in quite a while. Is there something I'm forgetting?
