Hi niko, I would like to have this in the future at some point.

But it is a pretty difficult thing to make solids deform and still keep joined edges within a good tolerance. As you may know this function was not available in Rhino either until the most recent 4.0 release.

Similarly it may be something like MoI v4 until that is possible to do directly inside of MoI.

Your best bet for this kind of deformation is to use Rhino for those operations, like jonah mentioned you can use Copy and Paste between MoI and Rhino to share objects back and forth quickly.
