I made a quick try - and it doesn't work very well, even when it should (between
a cylinder and a cone).
Example: http://www.brickshelf.com/gallery/Philo/Misc/cedgetst1.dat (cedge
primitive is here included). Cedge seems to behave correctly on the more sloped
cone, but not on the other, it appears when it should not. Maybe this is caused
by huge scaling factor?
One thing difficult with this primitive is that it can't be seen. No
visualisation in MLCad, and if you enable all edge lines/control lines in LDView
it mixes with condlines of cylinders/cones.

| (...) Looks like you found another LDView bug ;-). Zoom out and it works fine. It only doesn't work when the control points are clipped by the edge of the window. I'll have to figure out a way to fix that. (...) It's difficult, but by using polling (...) (16 years ago, 13-Dec-08, to lugnet.cad)
