Hi Psygorn, so as shown above it is possible to scale a box like you want using control points. That is not a general solution for all models though because of how NURBS models work with an "underlying surface" that has trim curves on it.

There is some information on that here:
http://moi3d.com/faq#Q:_Why_does_show_points_work_for_some_objects_but_not_others.3F

A box is a special case where it has all untrimmed surfaces and all the underlying surfaces have matching control points along the trim edge boundary.

In the future I do want to allow transforms like scaling to be applied onto a face in a more general way. It is a pretty difficult area to implement though because it involves extending and intersecting neighboring faces with the transformed face. That's why it doesn't do it yet.
