Is there a doc anywhere describing how to use the MLCAD hose
generator? I've been trying understand how all the points
contribute to the curve but must be missing something obvious.


If MLCAD uses Bézier curves to model the bent hoses, you may find some
information on the internet about this technique:

An interactive demo:

Here is a more mathematical approach:

You may also like to see my own description of how I handle this in
LDraw-mode:

(...) ldraw mode program to create flex hoses in the past with no problems, it's just this new way that is confusing me :-) Jennifer (22 years ago, 27-Dec-02, to lugnet.cad.mlcad)
