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.
