How floor plans are built
Floor plans come straight from the LiDAR scan geometry, and separate rooms compose into one home layout automatically.
You never draw a floor plan by hand. When you scan a room with LiDAR, the scanner already measures the walls and the footprint of every piece of furniture. Van Line Pro keeps that geometry, so the room's layout can be drawn on screen, orbited in 3D, and printed on the inventory. This article explains where the plan comes from and how separate rooms fit together.
Where the geometry comes from
- The wall outline, the doorway openings, and each object's footprint, size, and heading are all captured by the LiDAR scan.
- Only rooms scanned with LiDAR have a floor plan. Rooms added by photo, voice, or by hand carry no layout, so they don't appear on the plan.
How rooms compose into one home
When you scan several rooms in a single walk-through, the scanner keeps them aligned to one another as you go, so they share a single, drift-free coordinate space. Those rooms compose into one home layout exactly as scanned, with no extra work.
Rooms scanned separately are "parked"
Sometimes a room can't be confidently placed against the rest of the home, for example when it was scanned in a different session and its coordinates land on top of another room. Rather than guess, the app parks that room in a row beside the home, in a clearly provisional position, and draws it with a dashed outline.
On the plan you'll see this hint:
"Dashed rooms were scanned separately — their position is approximate."
Important: A dashed room's position is a placeholder, but its measurements are still real. The room's size and the pieces inside it are as measured. Only where it sits relative to the other rooms is approximate.
Good to know
- Standard ceiling height. The 2D scan doesn't record ceiling height, so the 3D model raises walls to a standard residential height (8 ft) purely so the rooms read as rooms. It is not a measured ceiling height.
- Footprints stay tied to items. When a scan is imported, each footprint is linked to the inventory line it became, which is what puts sticker numbers on the plan and makes pieces tappable.
