Wireframe instead of solid object

See original GitHub issue
import cadquery as cq

sPnts = [
    (10, 15),
    (30, 40),
    (70, 30)
path = cq.Workplane("XY").polyline(sPnts,includeCurrent=False).close()
result = cq.Workplane("YZ").circle(10).sweep(path)

Can anyone tell me why this code shows a wireframe instead of solid object? Is it a bug or am I doing something wrong?

Your code does not work for me and I think these are the reasons:

  1. The normal of the extruded faces needs to be aligned with the initial sweep direction.
  2. The extruded shape cannot be too big with respect to the sweep path (so that no self-intersections are created).
  3. For a closed C1 discontinuous path it is better to sue transition='right' or transition='round'.

Here is a working example, you’ll need to play wit the dimensions

import cadquery as cq

sPnts = [
path = cq.Workplane("XY").polyline(sPnts).close()
result = cq.Workplane("YZ").circle(4).circle(5)
result2 = result.sweep(path,transition='right')
