(...) Could you transform the co-ordinate system so that one of it's axes is along the centre-line of the 4-4cyls (in the plane S0-S1-S2), rotate it about that axis so that the longest sise is in the plane, then transform the co-ord system back? (...) (20 years ago, 6-Jan-05, to lugnet.cad.dev)

(...) Hi Roscoe, Thanks for the help. If you extend the cylinders so that the outside edges touch, you will be able to see the overlap.... at small angles, this works because the overlap is small, but at larger angles, the overlap is noticable. I (...) (20 years ago, 6-Jan-05, to lugnet.cad.dev)

(...) Hi Philo, Good to hear from you. My mistake.... I am using 4-4cyls.dat. rotating them to align them with the S0-S1-S2 plane is what I don't know how to do. Thanks, Kevin (20 years ago, 6-Jan-05, to lugnet.cad.dev)

(...) Why not just work out the longest side of the cylinder you need, and extend the hose segments by that much on each end? That would reduce the file size even more. BTW, if you do decide to go with your solution, and come up with a result, you (...) (20 years ago, 6-Jan-05, to lugnet.cad.dev)

Hello Kevin, (...) What about using 4-4cyls primitives placed to the end of hose segments? Scale their length to (hose diameter)*tan(angle/2). See example for a 30° angle: (URL) and (URL) know, this is not a full solution, you need to rotate the (...) (20 years ago, 6-Jan-05, to lugnet.cad.dev)

Hi, I'm a much better arithmetician than mathemetician and have hit a wall with LSynth. In an attempt to reduce file size, I've written an algorithm that merges hose segments together (based on an angle error limit). This dramatically reduces file (...) (20 years ago, 6-Jan-05, to lugnet.cad.dev)
