@MrJack88 The only way I’ve figured out so far is along straight path or where the “spring” has the same origin along a straight path. The three examples in the video was a break-through for me but all those are curved along the same Y-Axis where really just the radius changes. Conical spring is an example of this and is easy with this technique.
Revolve is not like sweep (although I wish it was). Sweep can work with a projected line or spline. Revolve does not handle that (from what I can tell).
I though maybe sweep (or loft) a circle but can’t figure out how I would cut the spiral.
