How can I create a spiral that follows an arbitrary bezier path?

Here's an example of this in Fusion 360:Example of goal So, in other words, this is a bezier curve that winds itself around another bezier curve to produce a spiral. The spiral profile, climb angle, and distance from the central bezier curve should all be customizable.

I gave a detailed answer about a phone cable here. If you want to keep a curve instead of a mesh you can do it the way below. At the end you can convert your curve to mesh if you want. I'm not sure you can use 2 curves and array a mesh along the spiral though. So:

  • Create a spiral.

  • Create another curve, a straight one this time. Give your spiral a Curve modifier with the second curve as Object.

enter image description here

  • Select your spiral. In the Properties panel > Object Data > Shape > Choose Fill > Full, and in Geometry play with the Bevel Depth and Resolution values.

enter image description here

  • Move the straight curve, the spiral will bend.
