Hi Tim, currently MoI does not have a function to deform a shape by starting with an initially straight shape and then bending it. So if that's what you need to do you'll need to instead use some other program that does that kind of stuff for that particular model.

Rhino has a bend tool that you could use for that, or also you could generate a straight shape in MoI and then export that to a poly mesh based program, many of which have those kinds of deformation tools in them (it's generally easier technically to deform a poly model than a NURBS solid model).

I do want to work on adding in some deform tools like that in the future in MoI though.

But for now I don't think that MoI will easily do what you need for this particular case.
