Twisted loft on a curving path

Hello, is it possible to twist a shape, in this case a square, around a curving path? I assumed it would require loft with a guide curve, but I can’t get it to work.


Another way if needed.


I drew something akin to a conical spring by revolving a wide flat rectangle and then intersecting it with a shelled truncated cone. It’s not exactly what you’re looking for, but it might be a starting point.


Creating the conical spiral is the easy part.

Creating a thread that follows the spiral would appear to be as simple as sweeping a thread profile along the spiral… but it’s not that simple…


First I create a profile

Switch to 3D view

Then revolve

Create a cone

Move cone to spiral

Intersect the two

Revisit the original profile

Create thread profile

Sweep profile along spiral to create thread

Looking good!

But don’t celebrate yet…

The thread becomes twisted as it progresses along the path of the spiral… FAIL! :frowning:

Any suggestions on how to do this properly would be most welcome :slightly_smiling_face:
