I am trying to create a coiled wire, which follows a non-circular helix path, with a non-circular (slot) profile.
The sweep path was created using an intersection curve between an extruded body and a helix surface.
When I sweep the slot profile, with no twist, it creates a twisted body. To get it to "not twist" I have to put in a twist value to offset the twist... confusing
How can I properly sketch the profile for the sweep so it stays untwisted?
Here is untwisted sweep:
Here is what it should look like (added an "offset" twist of 60 degrees):
I have attached the part.
