Lesson 4 of 13
Scan a level
Walk a level with LiDAR, and what to do if the scan stops.
3 min read
You scan a whole level in one walk: start in one room and carry the phone through every room on that level. BoxLi builds the walls, doors and windows as you go, then turns them into a level plan.
Before you start
- Open curtains and blinds, and turn lights on.
- Open interior doors, including closets.
- You don't need to move furniture. LiDAR reads the walls behind it, so you only need to see the perimeter of each room.
- Allow camera, microphone and location if asked.
During the scan
- Hold the phone upright at chest height, screen facing you, and point it at the walls.
- Walk slowly along the edges of the room. Let the outline of each wall fill in before you move on. Sweep up to the ceiling now and then.
- When you go through a doorway, scan the doorway itself, then keep going into the next room. This keeps the rooms joined up.
- Watch Covered level area at the top climb as you go.
- Cover every room on the level, including closets, halls, laundry and stairs.
The buttons on screen
| Button | What it does |
|---|---|
| X (top left) | Closes the scanner |
| Refresh (circular arrows) | Saves what you've scanned as a section and continues with a fresh one. Useful on big levels if the scan starts to lag. Nothing is lost. |
| Flashlight | Turns the phone's light on in dark rooms |
| Microphone | Records spoken notes while you scan. Tap to mute. Notes show on the dashboard's Voice tab. |
| Done | Ends the level. It switches on once enough walls are captured. |
If a message says Hold still or Stop moving until this clears, stop and hold the phone steady until it goes away. Point at furniture or corners, not bare walls means the phone has lost its place; aim at something with detail.
Finish the level
- Tap Done.
- On Finish this level?, tap Finish. Tap Keep Scanning if you missed a room.
- Wait while BoxLi shows Preparing your level plan. This combines the sections into one plan.
- The plan opens on the room labeling screen. Go to Label rooms and check areas.
If the scan stops
- Scan paused: you left the app, for example for a call. Come back to BoxLi and tap Resume.
- Return to the last scanned area: tracking was lost. Walk back to the room or wall where scanning stopped and move slowly until it recognises the area, then carry on.
- Discard this scan?: tap Save and finish to keep everything captured so far. Discard throws away the unsaved part.
- Memory or heat warnings: on very large levels BoxLi may save the sections it has and finish early to protect the phone. Scan the rest as another level or rescan from the property page.
