How to build a 3D spiral (not a helix)? I've been looking for ways to build a 3D spiral in Blender, but every time I search for it, I find techniques for building a helix.  I'm not looking for a helix; I'm looking for a 2D spiral, extruded up into the 3rd dimension.
Does anyone have any pointers for creating one?
Here is a tutorial for this:

Basically you use the shrinkwrap and the screw modifier to do this.

build a circle
use modifier screw and apply it
build a cone and scale and move it as you need it in the screwed circle
now use modifier shrinkwrap with object cone on your circle
scale z value to 0 so that you have &quot;flat&quot; screw
