I have been having some trouble executing a swept cut using a variable pitch helix along a tapered screw head. I have a custom thread profile I would like cut along a tapered helix. I can't seem to figure out how to make the thread profile cut along the tapered helix. I only get the error "Sweep Operation Failed to Complete". I have set up the sweep exactly the same way I set up a straight helix which has cut successfully. I've attached "Part 3" with the tapered helix and "Part 4" with the straight helix cutting successfully. Any help you can provide would be greatly appreciated, I have been at this for hours and I cannot figure out how to make it work. Thank you.
