v0.40

A coiled spring shape.

This is similar to helixSdf, but with the fixed height rather than infinite.

Parameters

Name	Description	Regular Handling	Read-Only Handling
Axis		Runtime	Semi-Baked
X: Y: Z:
Reverse		Runtime	Semi-Baked
Radius	The radius of the spring, i.e. the distance of the spring from the center axis.	Runtime	Baked
Height	Height or length of the spring.	Runtime	Baked
Coils	The number of rotations in the spring. Larger values mean a tighter coil.	Runtime	Baked
Thickness	Thickness of the spring, used when no cross-section SDF is attached.	Runtime	Baked
