Parameters

turns
Number of full rotations (must be > 0).
start radius (mm)
Radius at the center of the spiral (can be 0).
end radius (mm)
Radius at the outer end of the spiral.

How it works

Spiral produces an open 2D path (not closed). Use it with Spiral Up to create a single continuous spiral toolpath that climbs in Z, or combine with other geometry in a sequence. Ideal for organic or decorative spiral prints.
