Helo Michael!
Im new to the forum.
I saw your picture Ngon at Rhinos forum and Wow!
So your saying that you made torus, bollen difference with cylinder, got the shape and then just used meshing tool to produce this kind of a mesh with no triangles?
I do a lot of transforming from NURBS to DXF. I manage to do it, but yes its time consuming. But this way :-)

I saw MoI is in beta, what are your plans with it?
