I am facing a problem when I want to select a sub-part object by using cross selection it does not work. I am holding the left button and move the mouse from left to right but no object has been selected.
I think that would be a great enhancement to introduce a new selection command (after the tones of selection methods ) just like in Adobe or other vector graphics program there are two selections, one for the whole object one for editing the geometry. In rhino it could be two type of selection (click). Left click would select the whole object, Right click would select the sub parts (edge, curves, surface).
