Frequently Asked Questions
Everything you need to know about BoxLi, LiDAR scanning, and ANSI-compliant floor plans.
My tape measure is the most accurate tool available. Why should I use LiDAR?
A tape measure has served the profession well, but it has limitations — it can sag on long runs, tension varies each pull, temperature causes drift, and irregular spaces compound error. LiDAR uses laser pulses and a depth sensor to capture true 3D geometry, instantly detecting wall surfaces, corners, angles, ceiling slopes, and irregular room shapes. It performs a point-cloud scan that is more consistent than manually pulling a tape across a room. Tape is manual. LiDAR is mathematical.
ANSI 765 requires measurements to the nearest inch. Does LiDAR meet that standard?
Yes. LiDAR measures with sub-inch precision and eliminates rounding drift. Typical LiDAR depth accuracy on supported iPhones and iPads is within ±1% at ±10 feet (often better in controlled scan conditions). Because LiDAR captures thousands of distance points per second, it reduces accumulated rounding error, avoids inconsistent pulls, and produces repeatable measurements. You still apply human judgment for ANSI (ceiling height, above/below grade, finish level), but LiDAR ensures the dimensional data you base that judgment on is accurate and defensible.
Isn't it a requirement that measurements be done from the exterior to be ANSI and GSE compliant?
No. Neither ANSI Z765 nor the GSEs require that measurements be taken exclusively from the exterior. In fact, relying on exterior measurements alone can make it difficult — if not impossible — to remain fully compliant. ANSI Z765 requires you to correctly identify and exclude non-compliant interior areas, which you cannot do from exterior dimensions alone. BoxLi allows you to complete the entire scan from the interior using your LiDAR-enabled device — capturing interior wall measurements, room dimensions, and accurate exterior dimensions by applying the wall thickness you input.
Do I still need to redraw the floor plan at my desk?
No. The floor plan is generated instantly on your device. No CAD. No tracing. No measuring and typing into software later. Scan. Review. Done. This saves 20–40 minutes per assignment, allowing appraisers to complete more inspections and earn more.
Can technology replace the appraiser in applying ANSI?
No — ANSI still requires human interpretation. LiDAR measures space. Only the appraiser determines whether it counts as GLA, whether ceiling height qualifies, whether it’s above or below grade, and whether it’s finished living area. Technology measures. Experts decide.
What devices are supported?
Any Apple device with built-in LiDAR, including iPhone Pro / Pro Max (12 and newer) and iPad Pro (2020 and newer). If you’re unsure, the app automatically verifies LiDAR compatibility.
Who can use BoxLi?
Appraisers, property data collectors, real estate agents, inspectors, and insurance and underwriting professionals. No special equipment — just an iPhone or iPad with LiDAR.
Do I need training to use BoxLi?
No. The app guides you step-by-step and produces a complete, ANSI-compliant digital floor plan in minutes.
Can BoxLi export a floor plan into appraisal forms?
Yes. BoxLi exports to PDF (ANSI floor plan), JSON/structured property data (UAD 3.6 compatible), and via API or SDK into third-party software.
How long does a scan take?
Most interior scans are completed in about 15 minutes for a standard home.
How does this make me more money?
Less time measuring means more capacity and more revenue. BoxLi eliminates redrawing, hand measuring, and manual data entry. Appraisers can complete more assignments per day — without rushing or compromising quality.
How does the app address non-ANSI-compliant space?
All scanned area is displayed on the floor plan rendering, color-coded with labels identifying areas that aren’t in compliance (such as "unheated space"). These non-ANSI-compliant spaces are not included in the GLA calculation.
What if I return to my desk and realize I didn't measure a room?
Generally, that’s not a problem. The technology makes missed rooms rare, but if it happens there will be a gap in the 3D rendering. LiDAR measures negative space, so a missing closet or interior bathroom can be addressed in the in-app editor — no need to revisit the property.
Is BoxLi approved by Fannie Mae / Freddie Mac?
BoxLi is built to meet their digital floor plan and ANSI measurement criteria. The GSEs do not offer formal approval for measuring apps.
How is BoxLi different from other scanning apps?
BoxLi is ANSI-compliant, 100% automatic (data is not sent offshore for manual manipulation), requires no manual drawing, and produces structured data output.
What if a room is cluttered or furniture blocks the walls?
BoxLi’s LiDAR penetrates visual clutter — you scan the perimeter, not every object.
Can BoxLi be used offline?
Yes. Scans process locally and can upload when a network connection is available.
Can BoxLi be white-labeled or integrated into my existing platform?
Yes — SDK and API integration options are available for lenders, AMCs, software companies, and platform vendors.
