 | | Rect primitive with one edge missing?

|
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, (...)

(...) The 1-4con0 primitive should arguably have a different name, because it is a different shape than all the other cone primitives. Specifically, it comes to a point, while all the other cone primitives are missing the point (they're open at both (...) (22 years ago, 24-Jan-03, to lugnet.cad.dev)

I was updating part 3847 to use the 1-4con0 primitve and I notice some wierd shading at the tip. I then open the 1-4con0 primitive directly and there were no shading problems I could see. Download 3847 at the Parts Tracker to see what I mean. (URL) (...) (22 years ago, 24-Jan-03, to lugnet.cad.dev)

(...) 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)
