Note the 105 prolem is caused by a gap in the ogee, see ogeepolyPath(),
// Lower Right Outer arc
lro = [ for (i = [0:1:lowerpoints-1])
Remove the '-1' fixes that gap, and [0:1:105] is good geometry.
[Dan, same issue with ogeepoly()]
When I included reverse() the result is everything is inside-out.
(note on closer examination the cube() has no purple, that is an artefact)
Without reverse(), without show-edges:
Those purple bits behave as if there is z-fighting, when you rotate the
It gets very psychedelic:
I have no idea what's going on...
