Oh I read the mid$ and the drawing as figuring out which plane (surface) to draw.

Yeah that's it for sure, selecting a plane. But for some reason instead of "plane 1, plane 2" etc, or it uses the corner numbers and then grabs those from that string. It seems like a neat way to go about this. I would have had separate strings, like side1$ = "0246" and so on.

Anyone got a quick app? Eh, has to distinguish a single line IF with block IF to insert END IF's in correct place.

Playing with it a bit, I chopped it down for ease of reading and I come in around 120 or so, excluding comments and whitespace. Still impressive.

@MasterGy thank you for creating this program. Also for allowing left and right mouse button presses to adjust the light although the top of the program screen says "mousewheel" to do it. Heart One modification I would make is checking for "escape" key press to leave the program. But that's just me.
