Sub-Layers: Multiple Operations on the Same Geometry

Why this matters

Apply multiple cut or engraving settings to the same geometry without duplicating the object, and understand the ordering and compatibility implications.

How it works

• Sub-Layers allow multiple cut/engraving settings to be attached to the same layer geometry.
• LightBurn supports multiple Sub-Layers and each can have its own settings and Output state.
• Sub-Layer order matters because the operations are applied in the displayed order.

Practical workflow

1. Use Sub-Layers only when repeated operations genuinely belong to the same geometry.
2. Name or document the purpose of each Sub-Layer.
3. Check Output independently for every Sub-Layer.
4. Preview the complete sequence, including repeated processing of the same shape.
5. Test file compatibility before relying on Sub-Layers in older LightBurn workflows.

What to watch for

• A hidden or disabled-looking parent layer does not replace checking every Sub-Layer.
• Repeated operations can multiply heat and job time.
• Advanced layer structures are harder to audit months later, so naming and Preview become more important.
