How to create a progressive coil spring in Blender 2.82? I've been trying to create a coil spring with a progressive elongation of the spiral in the Z direction and so far have been coming up short. Seems like it's possible to scale the radius easily enough, but not the tightness of the spiral itself.
I've primarily been using the screw modifier to achieve a basic coil.
Does anyone have any suggestions? will I need to use a particular modifier combo?
First add a vert and use the screw modifier.



Then add a lattice and scale/move it in objectmode to the correct size and location. Also subdivide it alonge the Z-Axis.





After that add the lattice-modifier with the newly created lattice-object.



Now you can change the coil by editing the lattice-object in editmode.



So I did the fast method by just adding a skin-modifier and changing the size in edit-mode with ctrl+a.

You can also apply the modifiers and convert it to a curve and set it to nurbse...
