How to use Spiral Array

  1. Select the layer whose linework you want to transform
  2. Open Studio → Add Modifier → Pattern → Spiral Array
  3. A modifier node is appended to the layer stack (non-destructive)
  4. Reorder modifiers in the stack; later modifiers see earlier output
  5. Tune parameters in the modifier card in the right sidebar; preview updates on the canvas

Menu path: Add Modifier → Pattern → Spiral Array

Frequently asked questions

Where is Spiral Array in the menu?

Add Modifier → Pattern → Spiral Array

What can I adjust?

Start with the key controls above, then fine-tune everything else in the right sidebar inside Studio.

Is this non-destructive?

Yes. Modifiers run on the layer stack without destroying source elements. Reorder or remove the modifier node to revert.

Does Spiral Array work with multi-pen plotting?

Yes. Use Pen Palette on a layer to split linework by color, or set per-path ink on modifiers like Offset.
