This would be a great feature. And there is an increased need with the increase in digital manufacturing. It comes down to differentiating between developable and non-developable surfaces. A developable surface can be unwrapped accurately. I do this all the time on projects. I have experimented with both VW and Rhino. With VW I have seen some anomalies when using the existing Unfold Surfaces command on more complicated shapes. A non-developable surface curves in two directions at the same
