Layers are separate drawing surfaces within a takeoff. Every measurement you create belongs to a layer, letting you isolate different scopes of work, trades, or revisions on the same plan without overlap. Think of them as transparent sheets stacked on top of your plan.

Every project starts with a Default layer. New measurements land here unless you switch to a different layer first. The default layer cannot be renamed or deleted, and it is always listed first in the layer dropdown.

Open the layer dropdown in the takeoff sidebar and click New layer to add one. The new layer becomes active immediately, so any measurements you draw next belong to it.

Click the dropdown anytime to switch layers. A checkmark marks the active layer, and only its measurements appear on the canvas and in the sidebar. Select All layers at the top to show every layer's measurements at once — useful for seeing the full picture across trades or work phases.

Hover over a non-default layer in the dropdown to reveal its options menu (three-dot icon). From there you can Rename the layer or Delete it. Deleting permanently removes every measurement on that layer; if it was active, the view returns to the default layer.

Layers created by an AI takeoff are analysis layers. They can be renamed but not deleted, and their options menu adds a View history item. View history opens past versions of the layer and lets you revert to an earlier run — reverting snapshots the current state first, so it stays undoable.

Merging combines measurements from multiple layers into a single new layer. Open the layer dropdown and click Merge layers.... Select two or more layers in the dialog — the numbered badges indicate stacking order from bottom to top. Click Preview to see the combined result on the canvas.

A floating bar appears at the bottom of the canvas during preview. Click Merge to proceed, or Cancel to discard. In the confirmation dialog, enter a name for the merged layer.

By default, merging copies the selected layers' measurements onto the new layer and leaves the originals in place. Check Delete original layers after merge to remove the source layers and their measurements instead. Click Merge to finish.

Every measurement belongs to exactly one layer. Symbols group measurements, so a symbol appears wherever its measurements live. Switching layers filters the sidebar and canvas to the active layer's measurements.

To reorganize work after the fact, open a symbol's actions menu and choose Move to layer. This moves all of that symbol's measurements to the layer you pick.
