I've done some digging around in the forums, but can't seem to find an answer to what I'm trying to do and having some difficulty with.
What I'm trying to do: I'm designing part of a machine which consists of a feedscrew; each revolution of the screw advances one part along a conveyor. The part is basically an extruded oval.
Making a Helix and then sweeping the profile of the part along the helix doesn't work, because the material left over on the screw interferes with the part a few degrees before and after the point of engagement.
I understand the use of Solid Sweep (vs. Profile Sweep), and Solid Sweep should give me the effect I'm looking to create. However, Solid Sweep seems to only work with a cylindrical solid, not any other shape. As my part is an extruded oval, I can't quite think of a workaround for this.
Any suggestions? Attached is a part file showing the dilema - I want to make a Solid Sweep (Cut) using the body "Part Representation" and "Helix/Spiral1" features, but it won't allow me to make the feature.
Thanks in advance!
