I am trying to reverse engineer a feed-screw. The design has a variable pitch, variable diameter of helix, and variable profile. The profile is where I am having the trouble. The profile changes from 15mm to 14mm to 12mm at certain points. I have looked at multiple ways of doing this and I keep running into hurdles. What would be the best method ?
In addition, I have another feed screw that the swept profile intersects and I'm trying to do a swept cut which crashes. What would be the most efficient process? Swept surface profile, then close off and convert to solid and do a subtraction?
Any pointers are greatly appreciated.
