OK so i did it my way, no fancy plugins or scripting
The idea is actually not mine, someone helped me out. I just refined it a bit. So this is how it works:
- draw a nurbs circle & a path, extrude circle along path with rotation added, 2000 or so
- duplicate curves (surface can be dumped)
- extrude a smaller circle profile along duplicated curves, also with some rotation
- repeat previous steps with smaller tube, now extruding final geo
when i was done with a twisted pair i simply grouped them and duplicated 3x, with rotation 90 deg.
This may sound like a tedious workflow but in fact it's not that bad. Plugin images look gorgeous too but i just couldn't make the plugin work in a reasonable time so i thoguth i better do it manually. But i'll take another look at the plugin. Bunch of thanks to you guys.
