(...) It sounds like you want the intersection point of the 2nd circle with the plane of the first circle. I guess that should be exactly one point unless they're in the same plane. However, I don't see how the rubber band gets back to the first (...) (22 years ago, 21-Jan-03, to lugnet.cad.dev)

Don, I'm assuming four pulleys in this case. Two are parallel to each other where the rubber band bends to be non-planar, and two others that pull the band around the two parallel pulleys. Kevin (...) (22 years ago, 21-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)

<snip> (...) Yes. lsynth only deals with 1 peice of stretched rubber band at a time, which is why I was keeping those other three pulleys a secret from Don. Kevin (...) (22 years ago, 24-Jan-03, to lugnet.cad.dev)
