I agree, as an old Rhino user from back in the day, I enjoy MOI way more (not to mention the mesher is way better in MOI!) but I find sometimes trying to create certain forms just don't come out the way I would expect.

I was going to post a quick video later of something I was working on to get some suggestions as to what I was doing wrong.

Some tutorials on modeling with MOI would be helpfully!
