Hi Dzeko, re: #1 unfolding, unfortunately unrolling surfaces is a quite complex area of work because it's not mathematically possible to unroll just any curved surface to a flat sheet without stretching things, that's only physically possible with a special category of curved surfaces called "developable surfaces".

Surfaces in MoI are not restricted to only be constructed as developable surfaces, so it would be kind of weird to have an unfold surface tool which didn't work on most things that you constructed in MoI, there would probably need to be a whole set of special developable surface construction and analysis tools in order for that to really make sense, but that makes this a quite complex intertwined set of specialized features which is unlikely to happen in MoI anytime soon.

Rhino does have some of those tools though, if you need surface unrolling now you can use Rhino in combination with MoI to do it.
