I personally would be happy if MoI would concentrate on it's core strengths - great 3D modelling, easy to use, light on the eye, uncluttered.

For me, every improvement in the Fillets area would be the most welcome addition together with more deformations.
Not only variable width Fillets, but also better handling of cases where edges run down to zero width or where fillets come in contact with not only one patch but overlap or touch a second geometric feature.
Of course that is only my personal needs and YMMV.
I just wanted to state it anyway ;-)

For the other stuff I just bought ViaCAD Pro last night.

Cheers,

Tom
