Helix difference extrusion yeilds staircase effect #489

Description

@kalle

System information

SolveSpace version: 3.0-7f9117b2bf0

Operating system: Fedora

Expected behavior

When selecting "force NURBS surfaces to triangle mesh" for a helix extrusion I though "chord tolerance" in the configuration menu would somehow influence the size of the triangles since it makes cylinders etc smoother.

Actual behavior

The slope of the helix in the attached model is very coarse, almost a staircase. In this model I have lowered the tolerance to 0.05% to no avail.

Additional information

If there is a way to control this, it should perhaps be more prominently positioned.
