Scan a room with AR

Use the mobile app’s AR scanner to measure a room or wall on site and save a dimensioned floor plan straight to the space.

The AR scanner starts from the add menu inside a space. Drop points around the room’s outline with the on-screen reticle, then save to produce a dimensioned floor plan image attached to that space.
  1. 01

    Check your device

    AR scanning is available in the mobile app on iPhone, with elevation capture on Android. iPhones with a LiDAR scanner, such as the Pro models, give the most accurate measurements.

  2. 02

    Open the space

    Open the project, then the space you want to measure. Tap the + button and choose Floor Plan — on Android the tile is labelled Elevation.

  3. 03

    Choose what you are measuring

    When asked whether you are taking a floor plan or an elevation, choose Floor Plan for the room’s footprint or Elevation (Wall) for a wall run.

  4. 04

    Mark the outline

    Aim the centre reticle at each corner of the surface and tap + to drop a point. Every segment shows a live measurement as you go, and closing the shape completes the outline — use the undo button to remove the last point, or the new-measurement button to start a separate shape.

  5. 05

    Name and save the plan

    Tap the save button and give the dimensions a name, such as Room Dimensions. The app draws a dimensioned plan and saves it to the space as its floor plan, ready to view there and in the web portal.

Good to know

  • Move slowly and keep the whole surface in view — good lighting and steady movement give cleaner points.
  • The scan saves to the device first, so you can keep working without signal and let it upload on the next sync.
  • The camera button inside the scanner saves a plain photo of the AR view as a space image instead of a floor plan.
