I am having an issue with getting a sweep to work on a 3D sketch. I used the equasion curve to get my variable pitch to work but am having a problem getting the sweep feature to accept it. It say that I have self intersecting surfaces. I have attached the file and would greatly appreciate some help with this! THANKS in advance!
I haven't opened the file, but assuming this is a coil spring sort of problem, the coils can't be in contact with each other. You need to have a gap, miniscule as it may be. You could shrink your profile 0.001" or so and see if the problem clears.
Can you attach the file as a jpeg instead (much much smaller file size - I am on a slow connection with limited download.
Something like attached?

Ah! A conveyor's bottle separating screw. You may need to do the sweep as two cuts, each not self-intersecting. (Left and right halves of the groove's profile as shown in the photo, if you catch my meaning.) They can intersect each other, just not themselves.
