Room segmentation
Room boundaries, doors and passages, mapped across the storey.
From laser scan to as-built plan
Upload an E57 file — get rooms, measurements and a floor plan
DefiniLine analyses point clouds from laser scans of existing buildings. Our engine finds the floor and ceiling planes, separates walls from openings, splits the storey into rooms, detects objects, computes areas and volumes, and produces an architectural plan ready for CAD. No installation, no software licence — a browser is enough.

How it works
-
Upload the scan
One E57 file (ASTM E2807) from any terrestrial or mobile scanner — Leica, FARO, NavVis, Matterport and others. The upload is encrypted and chunked, so a multi-gigabyte file uploads in the background with a real progress bar.
-
Automatic analysis
Our pipeline runs in defined phases — from reading the header to the final report — and each phase is validated against a data contract before the next one starts. Progress is shown on a status page you can refresh at any time.
-
Download the results
A measurement table per room, JSON/CSV for further processing, a floor plan in SVG and DXF, and a summary HTML report. Every figure is also given as text in an accessible table, never only as an image.
What you get
Areas and volumes
Floor area, height, volume, gross and net wall area — per room and for the storey.
Doors and windows
Width and height of every opening, the wall it belongs to, and a CSV export.
Objects in the space
Furniture and equipment grouped per room, including wall-mounted elements.
Floor plan
An architectural drawing with walls, openings, room labels and dimensions — SVG and DXF for CAD.
Summary report
A single HTML page with every image, table and parameter used in the run.
Transparency, privacy and accessibility
- Every number shown comes from the engine's own output. We do not invent results, and if a phase fails we say so plainly.
- Your scan is kept only for the analysis and is deleted automatically within 7 days, or immediately on request.
- No tracking cookies, no advertising, and no sharing of your data with third parties for marketing.
- The site was designed for accessibility from the start: full keyboard navigation, screen-reader support, conformant contrast and text alternatives.
