Re: [Visualpython-users] Rotating a helix about its axis.

[Bruce S. <Bru...@nc...>]

Thanks for pointing out this bug. Here are two work-arounds:

1) Put the helix in a frame, and rotate the frame object.

2) Rotate the axis of the helix:

	h = helix()
	h.axis = rotate(h.axis, angle=pi/2., axis=(0,0,1))
