Ceiling Scanning

Capture ceiling geometry using the dedicated ceiling scanning mode with mesh capture.

Ceiling scanning mode

Section titled “Ceiling scanning mode”

The ceiling scan feature uses:

  • Mesh capture - Ceiling surface geometry
  • Real-time visualization - Live mesh preview in AR view
  • Start/Stop controls - Begin and complete scanning

Scanning a ceiling

Section titled “Scanning a ceiling”

  1. Open Ceiling Scan

    • Select ceiling scan option
    • Wait for system to initialize

  2. Start Scanning

    • Tap Start button when ready
    • Tilt device upward 45-60 degrees
    • Point at ceiling

  3. Scan Coverage

    • Slowly rotate in place while looking up
    • Walk around room with device tilted up
    • Watch mesh preview fill in with green overlay

  4. Complete Scan

    • Check mesh coverage for gaps
    • All areas captured
    • Tap Stop button to save the ceiling scan

AR View display

Section titled “AR View display”

The AR view shows:

  • Green mesh overlay - Ceiling areas that have been captured
  • Gaps - Areas needing more coverage
  • Real-time updates - Mesh fills in as you scan

Coverage patterns

Section titled “Coverage patterns”

Center rotation:

  • Stand in room center
  • Slowly rotate 360 degrees
  • Keep device tilted up

Perimeter walk:

  • Move to room edges
  • Walk along walls with device tilted up
  • Capture ceiling-wall junctions

Troubleshooting

Section titled “Troubleshooting”

Incomplete mesh coverage:

  • Scan from additional positions
  • Improve ceiling lighting
  • Hold device steadier

Gaps in mesh:

  • Return to areas with gaps
  • Scan from different angle
  • Adequate lighting

Mesh not updating:

  • Hold device steadier
  • Point directly at ceiling
  • Check tracking status

Tracking issues:

  • Point at textured ceiling areas
  • Improve lighting
  • Avoid reflective surfaces

Lighting

Section titled “Lighting”

Turn on all ceiling lights for better mesh capture. Poor lighting reduces mesh quality and coverage.

Sloped walls and ceilings

Section titled “Sloped walls and ceilings”

In attic spaces with sloped ceilings:

  • Slant check - The app checks whether the scan includes slanted wall or ceiling geometry
  • Verify geometry - Check that the ceiling slope looks correct in the 3D preview
  • Rescan if needed - Use ceiling scanning mode if the shape isn’t captured accurately

Slanted windows

Section titled “Slanted windows”

When a room scan includes slanted geometry and no window note has been added, the app asks Are there any slanted windows? before you move on.

  1. Complete the room scan normally

  2. Review the sloped geometry in the 3D preview

  3. If the room has a Slanted window, tap Yes, add a window

  4. Add the Window note

  5. If there are no slanted windows, tap No slanted windows

Completing the scan

Section titled “Completing the scan”

Stop when:

  • Entire ceiling covered in mesh
  • No significant gaps
  • Ceiling-wall junctions captured

The scan is automatically saved when you tap Stop.
