Hi Dmitriy, I'm sorry if what I've wrote above has discouraged you, I was hoping to explain some of the reasons why some kinds of NURBS features like continuity controls have not been a focus for the earlier stages of MoI. The primary focus has been more on being able to build things quickly from 2D curves basically. It's more like "build a shape with some curvy elements (like some revolves and sweeps and such but not 100% completely composed of them) really quickly".

Probably this main initial goal does not really coincide with what you need to do, that's probably what makes MoI not quite suitable for you without some of these particular features.

I do definitely agree with you that more continuity controls would be helpful and it is indeed something that I am working on. I'm not entirely sure if it will get to the level that you need or not, there is a certain point of difficult to use functionality that just does not fit in with MoI's overall philosophy and direction.
