# Measure Volume as Layers

Moasure supports adding [**volume as an additional layer**](/en/use-cases/measure-volume-and-3d-terrain.md#measuring-volume-as-a-layer), allowing you to return to a site later and measure volume based on a previously recorded perimeter. This is especially helpful for landscaping, turfing, or excavation projects where you capture the surface first and the volume at a later time.

#### Before You Begin

* Ensure your original measurement includes a clear, straight **A–B reference edge**.
* Mark **Point A** and **Point B** with visible markers (such as flags or cones) so you can easily return to them for alignment.
* It’s also recommended to mark your **initial surface area starting point (Point C)** so you can return to the same position when capturing volume data.

#### How to Add a Volume Layer

1. Open your saved measurement, then tap the **Layers** icon.
2. Tap **Add Layer**.
3. Return to **Point A**, then walk to **Point B** to retrace the reference edge - look for the black alignment line on screen.
4. Moasure will switch to **Ignore Line** mode, letting you walk freely to your starting point inside the perimeter (mark this as **Point C**).
5. Switch the path type to **Points**, then capture elevation data using a spiral or zig‑zag pattern. Use more points for uneven or sloped surfaces.
6. Return to **Point C** to capture your final point and tap the red **stop icon** to finish the layer.

#### Viewing Volume Results

* Tap **3D Mesh view** to see volume calculations.
* Choose between:
  * **Lowest Point Plane** – uses the lowest elevation as base (great for holes and excavations).
  * **Perimeter Plane** – uses the outer edge elevation as base (ideal for stockpiles or raised areas).

#### Advanced Tools (Edit Menu)

To access more tools, tap **Edit**, then:

* [**Cut & Fill**](/en/moasure-app/master-edit-tools/cut-fill.md) – estimate how much material to add or remove to level the surface.
* [**Add Depth**](/en/moasure-app/master-edit-tools/add-depth.md) – calculate volume below the surface—perfect for planning excavations.
