Demo of knurled cylinder (by Olivier Cruilles)
Hello all,

Just a little demo file in case someone is interested.

Absolutely fantastic !

Very cool! But there are naked edges :(

Very nice! It seems fine to leave "force to triangle mesh" until the second helix. The first one works fine with NURBS. For helicals you may find the "twisted extrusion" method better or not. I'll attach an alternative construction where you can more intuitively change the skew of each set of grooves by dragging or constraining on the end of the cylinder.

Is that a problem that you have open contour there ?

The open contour in the first sketch is OK. The rotate group is closed because the ends of the contour all line up. The angle is 18 degrees and there are 20 copies. The rotate group is then extruded/helixed perpendicular to the sketch plane.

This has led to finding a new bug with Helix. When doing helix along an axis perpendicular to the sketch, constraining to one of the ends doesn't work right. Thought I found the code fix but then it constrains to the opposite end as selected.

Helix was supposed to be easy, just offset some NURBS control points along the rotation axis of a revolve... It's been one issue after another ever since :-)

Yeah, I appreciate your work on Helix. Really critical functionality to Solvespace being a general and all purpose CAD.
