I am a native Creo (Pro/E) user using SW for the past 8 months or so. I used to do a lot of surfacing in Creo for my previous job for nesting and part contours. you could make things independent once you have the surfaces you want. i would like to do this in SW so that I could get a general shape, move on, change something higher up in the model tree and not have it break things that follow it. Thanks!
