This question is mostly for Fredrik but anyone else that wants to chime in is welcome. Have a look at this rendering: (URL) some reason these flexible axles didn't create right. They have a kink in the middle instead of a smooth transition. I (...) (22 years ago, 20-Oct-02, to lugnet.cad.dev)

(...) This is a very difficult situation to model. The fact that the end points are parallell make it difficult. Since there is little or no slack for the curve to curve itself in this case, you must make sure that the length of the curve is not (...) (22 years ago, 20-Oct-02, to lugnet.cad.dev)

(...) I am also curious how ldraw mode generates the control points. Lately I've been working on a hoser for ldglite based on some code donated by Chris Daelman (which was based on the hoser spreadsheet). I've been experimenting with with ways to (...) (22 years ago, 21-Oct-02, to lugnet.cad.dev)
