Organizing with layers

Every markup and measurement in Notch sits on a layer. Layers are how a marked-up set stays readable: one per trade, per review round, or per author, each toggleable on and off.

The Layers panel#

Open Layers in the right sidebar to see everything on the document, grouped by layer, with anything unfiled under No Layer. Add a layer with New layer in the header, click any item to select it on the canvas, and delete selected items from the header.

Measurements and page overlays nest under layers too — a takeoff or a revision overlay can live on its own layer just like markups.

The active layer#

Click a layer to make it active — it's highlighted, and everything you draw next lands on it. Click No Layer to stop filing new markups anywhere.

Managing layers#

• Rename — double-click the layer's name.
• Reorder — Move up / Move down in the layer's ⋯ menu.
• Delete layer — also in the ⋯ menu.
• Move markups onto a layer — drag them onto it in the panel, set their layer in Properties, or right-click on the canvas and use Layer.

Visibility is yours#

The eye toggle hides or shows a layer — for you. Visibility is per person, so hiding the electrical layer to read the structural markups doesn't change what your teammates see.

Patterns that work#

• One layer per trade during takeoff, then group the Measurements panel by layer for per-trade totals.
• One layer per review round (Rev A comments, Rev B comments) so old rounds can be hidden but never lost.
• A layer for revision overlays, shown only while comparing.
