Hi Klaus… yes!… exactly what I need! I looked through the code for quite a long time, and found that it’s too complex for me. I’m still learning. Is there a to get a simple solution… a tube, and change its shape tow ar three times? Maybe there isn’t such a thing. I’m writing a physics simulation- I’…

I can remove everything that is not essential to the core of the matter. And then comment on the remaining lines in detail. But it will take some time—it’s the pre-Christmas period. :slightly_smiling_face:
