(...) 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)

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)

Simply add LS40.DAT on each end of the axle, and you have a complete (...) (20 years ago, 5-Jan-05, to lugnet.cad, lugnet.cad.dev)
