Turn a scanned or paper plan
into a workable CAD file
An old paper plan photographed, a crooked scanned PDF, an archive drawing: FloorScan's AI reads pixels — no vector file needed — detects walls, doors, windows and rooms, then exports a multi-layer DXF at real scale. Manual vectorization takes hours; this takes 30 seconds.
Photo, scan, PNG, JPG or raster PDF — no vector file required
Where manual CAD redrawing takes 2 to 6 hours per storey
Separate CAD layers + area schedule, from the same scan
AI replaces manual redrawing, not just tracing
Auto-vectorization tools turn your scan into thousands of meaningless little strokes: the resulting "CAD" file is unusable for real work. FloorScan does semantic recognition: the AI model, trained on architectural drawings, identifies each wall (load-bearing or partition), each door with its swing direction, each window, each room with its name. Those objects — not strokes — are what gets exported.
Unknown scan scale? FloorScan infers it from standard door widths, from a visible 1:S scale, or you set it in 2 clicks on a known dimension — or by entering the property's total area. The exported DXF is in real meters, ready for AutoCAD, BricsCAD, Revit or QGIS. And the built-in editor lets you fix the detection before export: a missed wall is redrawn in seconds.
From paper to project, no redrawing
Photos and scans accepted
Raster PDF, PNG, JPG, smartphone photo — the AI works on the image, not on vectors.
Semantic recognition
Load-bearing vs partition walls, doors with swing, windows, named rooms — objects, not strokes.
Scale without a title block
2-point calibration on a known dimension, or recalibration from the property's total area — even on a photo.
Correction editor
Poor-quality scan? Add or erase walls and openings before export — undo/redo included.
Multiple output formats
Multi-layer DXF, area schedule Excel, annotated PDF report, structured JSON — from the same scan.
Archives and renovations
The killer use case: digitizing stocks of old paper plans for energy renovation projects.
Frequently asked — scan to CAD
What's the minimum scan quality needed?
A sharp document where walls are distinguishable by eye: 150 dpi is usually enough. Smartphone photos work if the plan is shot straight-on and well lit. The higher the line contrast, the better the detection — and the built-in editor catches doubtful areas before export.
The plan has no dimensions or scale — can I still use it?
Yes. FloorScan first estimates the scale from standard door widths (90 cm). For final precision, two one-click options: enter the property's total area (listing, deed, EPC) — everything recalibrates automatically — or calibrate on any known distance (a room's length, the building's width).
What if the AI misses a wall or invents a door?
That's expected: before export, the editor shows every detection overlaid on the plan. Add a wall with the brush, remove a false door with one click, redraw a room boundary — every fix updates areas and exports instantly. On a decent scan, these touch-ups take under two minutes.
