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.

Separate CAD layers + area schedule, from the same scan
Five steps to
complete analysis
PDF Import
Drag your construction plan in PDF format. Or load our sample file to test immediately.
Crop
Select the area of interest with the interactive cropping tool. Focus on what matters.
AI Detection
Our AI model analyzes the plan and detects all architectural elements with confidence scores.
Validation
Verify, correct or complete each detection in the interactive validation interface.
Export

PDF Floor Plan to DXF in 30 Seconds (Stop Redrawing) | FloorScan
Drop a PDF plan, FloorScan detects walls, openings and rooms, and the Export menu returns a DXF that opens in AutoCAD, to scale and sorted by layers.
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.
