Summing several roof and wall faces (web and app)

If you need the combined area of several faces, you can sum them – both on the web and in the app.

Summing several faces on the web

1. Hold Ctrl (Windows) or Cmd (Mac).
2. Click the roof faces or wall surfaces you want to sum — selected faces are highlighted in the model.
3. The combined area is shown in the measurement panel on the right in the web window, together with the selected faces.

Summing several faces in the app

1. Press and hold a roof face.
2. Choose «Select several».
3. Tap the faces or buildings you want to include.

The app adds them up and shows the total. This works in WP Befaring on iPhone, iPad and Android. Read more in Roof measurements in the app – edges, leaving out and summing.

Selecting at different levels

You can select individual faces or entire rooms, floors or buildings.

The feature applies to both roof faces and walls, and measures the whole face — not just a single panel.

Note: If you combine interior and exterior scanning, an AI agent can calculate the exterior wall area even more precisely.
