Hello,
I’m trying to make a pipe spiral rest along a surface. I have created a spiral path and used a pipe tool with the curve. I would like the resultant pipe be tangent to the surface and not intersect.
I know for a straight cylinder I could just offset the helix by the radius of the pipe, but how do I handle the dome portion of the cylinder?
your curve is a bit wacky at the bottom (I reduced it for this example) - if you make a brep equal to this mesh then it’s easy to cheat it this way with brep normals from closest points. Wraparound_help.gh (90.3 KB)
