Hi, there was a ticket about ArcWall to support Parabola, Hyperbola, BSplineCurve, Ellipse, and BezierCurve etc.
ArchWall support Circle with Face - so it create kind of solid circular column type of object. But it does not support Circle w/o Face - so it does not create a Wall in circular form.
Testing to tweak DraftGeomUtils.offsetWire() so that the latter is supported... No idea how to support other geometries, anybody?
Then - ArchWall on Circular Face as Solid Circular Column object
Now - ArchWall on Circular Wire as Circular Wall
