i would like draw a shower hose:
the most obvious method colul be draw a pipe path (Green) magenta , an helix around (blue) and surface 1 rail , then boolean difference and voila!
But … the red thing keeps twisting by himself while going …
Other way : OffsetCrvOnSrf the helix then some surface between 2 helices, create a solid and boolean difference. No way the offset create miriads of curves that not join and the distance between the helices varies along the path.
is there a way to get the thing working?
