currently my students use _pipe with small (0.3 mm) radii to mark drafting lines on 3d-printed parts. The parts serve as prototype / molding. There is some struggle with Boolean Union / Difference, which seams to be related to the Surface Seam and Knot structure of true Circles.

_circle deformable, around curve

_sweep1

give more robust results - and enough precision

so maybe it would be nice to have a deformable option for:

_pipe

_cylinder

_torus

(and all other circular / similar commands ?)

???

and would be nice to allow Degree 1 starting with 3 points ( a Polygon like curve in sectionâ€¦

Degree 1, 4 points will result in a square like pipeâ€¦

I am not in a hurry with this wish - but it would be nice to have.

kind regards -tom
