immortalx, your English is most likely better than mine. :) Thanks - really like how you put that. Having spent a year working with Fusion 360 - happily just now getting to feel a bit familiar with MoI. As you implied MoI or NURBS modeling is a different mind set - which has only recently begun to sink in. One thing that has become evident is that regardless of how frustrated I get - MoI is ceaselessly interesting and a lot of fun. The forum here is the most helpful around. My wife thinks I'm addicted - she may be right. Also, it is beyond me how Michael Gibson manages answering all the questions with all the other plates he spins - it is rare indeed to have that kind of hands on owner these days.
