Thankyou Michael. I understand this feature isn't is as straightforward as one might imagine, and that poly modelling and CAD are two very different things.

As a feature request, individual editing of components like faces would be very close to the top of my wishlist. I think in general, for new users coming from poly-modelling or packages such as Maya, Max or Modo, it would also greatly help to cushion the transition to nurbs and strengthen the 'ease of use' reputation of MoI. As a poly modeller, it's a very natural inclination to want to just rotate a face this way or that, or scale an edge up or down. And it's easy to miss that kind of tweaking of surfaces when getting to grips with MoI.

Anyway, lots of work I'm sure. And not a dealbreaker by any means. For the future though, this would be a great addition.

Thanks for your explanation.
