Short description of error
Instead of creating a helix/spiral with minimal number of vertices for NURBS or Bezier output, it simply creates straight line segments as if it was approximating by mesh.

Exact steps for others to reproduce the error
Add Curve > Curve Profiles / Spirals > Helix (3D) / Archemedian (sic) and set Output Curve Type to Nurbs or Bezier.

In addition:

  • it should be spelled "Archimedian"
  • changing output curve type set all hidden objects to visible
