Layers
Organize markups into separate layers for complex documents. Every PDF automatically starts with Layer 0 (Markup) as the default layer.
Creating Layers
Type a layer name in the input field and click the + button. New markups are placed on the active layer.
Layer Controls
| Key / Control | Action |
|---|---|
| V / v | Toggle layer visibility (Visible/Hidden) |
| L / U | Toggle layer lock (Locked/Unlocked) |
| Up / Down | Reorder layers (affects rendering order) |
| Del | Delete layer (markups move to default) |
Moving Markups Between Layers
Right-click on the markup on the canvas → Move to Layer → choose the target layer.
Use Cases
- Discipline separation: Architectural, Structural, MEP markups on separate layers
- Review rounds: Each review cycle on its own layer
- Status tracking: Pending vs. Approved markups
- Client presentations: Hide internal review notes, show only final annotations
Tip: Hidden layers do not export to PDF — use this to keep internal working notes separate from deliverable annotations. Layer 0 (Markup) is always visible and cannot be deleted.
