I added Swirl under Add Modifier → Effects. Twist the input around a swirl centre.
How to use Swirl
- Select the layer whose linework you want to transform
- Open Studio → Add Modifier → Effects → Swirl
- A modifier node is appended to the layer stack (non-destructive)
- Reorder modifiers in the stack; later modifiers see earlier output
- Tune parameters in the modifier card in the right sidebar; preview updates on the canvas
Menu path: Add Modifier → Effects → Swirl

- Layered linework exported as G-code with pen-up travel
- Combined with other V3 objects and modifiers in the same document
Frequently asked questions
Where is Swirl in the menu?
Add Modifier → Effects → Swirl
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 Swirl 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.
