Is there a primitive for a rectangle with one edge missing? I can't seem to find one, and I think it would be useful. It certainly would for a part that I am currently working on -- reducing three lines of code to one, 48 times. If there isn't one, (...)

(...) What you really need is to find a way to find just one side of the "rubber band". Say, pulley A to pulley B, "Side one". Then you could use the same function to determine pulley B to C, side one or two, and so on... Right? Paul (22 years ago, 24-Jan-03, to lugnet.cad.dev)
