This is a very good program one that works in the same filed as AutoCAD.

Hi Iwan, there are definitely cool things in there, but also very focused on mechanical part design.. MoI is not focused so exclusively on that.

It is pretty difficult to implement all that kind of editing and manipulating kind of stuff with NURBS, it isn't something that I expect to have implemented in MoI anytime soon.

But I think that SpaceClaim has good support for the .3dm file format, so it should be easy to use SpaceClaim and MoI in combination with each other.

Yes, complex editing operations on polysurfaces imported from MoI/Rhino to SpaceClaim using 3dm file format are possible. However, when I used to edit (e.g. did shelling) "free-form" kind of objects rather than mechanical one I usually ended up with invalid object when checking in Rhino.
I also disliked a concept of "active command" and user interface that puts big and small button icons together - it isn't clearly arranged.
But for changing a fillets, moving a face or other "simple" editing operations it was very very handy...

This is going to become more common as more programs copy the Microsoft "Ribbon" style interface.

But the Ribbon was designed particularly for Microsoft Office. Some of the things like icons for Bold, Italic, Underline, etc... are so commonplace and pervasive that MS Office can get away with little icons for these things without really losing comprehension.

But I don't think that the same holds true for other applications.
