Hi, I’ve tried a few ways of doing this. Sweeping along spiral curve with profile curves seams flipped opposite, bending with symmetry on and off, twisting a flat polysurface, cutting a straight section in the middle at a 30deg angle and flipping over the one half to form a 60deg angle and again bending and twisting etc…
Used a piece of paper strip to visualise the method but just can’t get it just right with a mouse.
US size 8, UK 57
using subd will allow a 2-step-flowalongSrf aproach:
- draw a z (or s) shaped belt (front)
- flow it along a U-shaped surfaces
- flatten the left and right part
- flowalongSrf to the ring
- i needed to fix the subd’s normals
- offsetSubD
above workflow might (partially) work with History.
The SubD at the beginning might profit from another face layout- the already reflects later deformation…
EDIT
second version
same workflow as above - but the initial subD 's faces are more parallel to the first deformation - parallel to the overall axis.
split it at the cylindrical part should result in a nice ToNurbs surface for further steps / edit.
hope this helps - kind regards -tom

Great.This points me in a good direction. Will definately try this. Thank you so much for the effort.
