What it returns
Section titled “What it returns”A tool result: a verdict (pass, warn, fail or unknown), metrics, checks and findings, each with its source.
- Draws on the building: pins on what it found; a route with its narrow points; a box or 3D model placed in the room.
- Panel blocks:

How it works
Section titled “How it works”Driveway fit: how long and wide the driveway is, how many cars park on it, and whether a long vehicle (trailer, RV, boat) fits off the street. From above: Vexcel’s detector boxes the driveway, the parcel line ends it at the street, and the orthophoto’s paved colour gives its width at stations along it. With a scan whose garage door was recorded, the driveway starts at that door and runs out from it; otherwise it runs from the house toward the driveway box. Aerial estimates: medium for length (parcel lines and the scan’s placement are good to a couple of metres), low for width (colour edges, shade and parked cars).
Reliability
Section titled “Reliability”Every metric and finding carries its layer, its method and a high, medium or low label, set by the tool for each value. See findings and reliability.
Limits
Section titled “Limits”- Needs: aerial photo, aerial property facts. On a scan without them, the verdict is
unknownand says why. - It is slow: progress steps reach the workspace while it runs.
- A result is a planning aid, not an inspection.
On the made-up test home
Section titled “On the made-up test home”This section was written by running the tool when the docs were built, on a hand-made RoomPlan export (no real place was scanned), with no sponsor keys and the network switched off.
Cannot answer here Scan u_testhome0001 has no location (a phone scan carries none), so the aerial photo cannot be found. Give a latitude and longitude to run this on the site.
A phone scan has walls, doors, windows, rooms and objects, but no location, no photos and no property record.
