Hi orginatix, welcome!
I see two possibilities, both uses curves as central element:
- with only curve
- just make a spirally curve. Then under the curve properties > geometry > bevel add some depth to it et voila!
- to make it thinner at the and you need another curve that defines you taper/profile and link it under geometry > taper object of the spiral.
- a long tube with a curve modifier:
- again spirally curve
- for geometry add a long subdivided cylinder (or whatever) and align its origin exactly with that of the curve.
- add a curve modifier to the cylinder referencing the spiral.
To melt it all together I would add a remesh modifier on top
I’m convinced your toping will look 100% more delicious than mine!
