A shrinkwrap tool that works similar to Blender shrink modifier, would be useful for reverse engineering. This feature should work on both polygon mesh and NURBS as the target, the source in this case is a NURBS. I want to shrinkwrap selected CVs to my target object in X,Y,Z. If no CVs are selected then assume I want to shrinkwrap all CVs in that sheet. In my image I want shrinkwrap all the CVs in this sheet along the X axis to my target object(a polygonal mesh).
