3. You can either import your existing floor plan or create one now by scanning your room. Click 'AR Scan'.
4. Start with a corner of the room as the first anchor. Aim at it and click the '+' button below. Repeat the process until you've done so for every corner of the room and click the tick button when you're back to the first anchor.
5. Click 'Done' when your scan is finished.
6. You can now add a door, a window or even a text (to specify room names for example). Click 'Save' when you're done editing to add the floor plan to your LiveTour.
7. Click on the top right corner to choose the length/area unit.
