A loft to a point is automatically ruled.)

I think the whole thing could be made more general by using the same algorithm using the straight iso-lines as the folding edges - as obtained from the Curves|Isolines tool. But I need to think and experiment more before trying it...
I think that it could be not too difficult to generalize it for a cone shaped, that have three edges, considering the "point" of the cone as first parameters for every LineSegment.
More complex cases, could be achieved, I'm not so skilled in geometrical things to go over these cases.
