Hi D - I don't really expect for MoI to include that kind of pattern cutting calculation as a built-in function, it just isn't an area that I have very much experience in.

Eventually MoI will have some kind of extension system that will make it possible for other people to add stuff in, and I wouldn't be surprised if some other party might create an add-on to do that. But it will be quite a while before that will really be possible.

If the Rhino one does what you need, then I'd just suggest that you use that one. That doesn't mean that you can't use MoI - you can easily use MoI and Rhino in combination with one another since they use the same file format.
