Inconsistent rotation at profile sweep along non-circular spiral path

Dear Fusion 360 Community,

I noticed an expected behavior in the rotation functionality of the sweep tool.

I designed a non-circular body, that I created a spiral on using the intersection of a spiral plane with that body. Therefore, I have a non-circular path along that body, which moves up the body in an even spiral fashion. I then created a plane at the beginning of that path and designed a rope shaped profile.

If I then sweep that profile along the path and enter a rotation of e.g. 3000 degrees along the whole model, I notice 2 odd behaviors:

- It is only possible to generate the sweep for very specific rotations

- The rotation, once possible to generate is inconsistent along the path. At some points it has a strong rotation, while small at other segments.

I attached the model to the post for further debugging.

I'd love to get information about that unexpected behavior and also get suggestions on how to more properly design that rope spiral. 

Thanks!

 

Greetings, Phil
