ComparisonBest AI tools to convert floor plans to CAD (2026)
"Convert a floor plan to CAD" covers a few different starting points — a plan you already have, a space you need to capture, or a drawing you want hand-checked. There's no single "best" tool; there's a best tool for your situation. Here's the honest map, grouped by approach, with what each is good at.
1. AI web converters — fastest for a plan you already have
Upload an image, PDF, or scan; AI detects walls, rooms, and openings and exports editable DXF/DWG. No install, no CAD license to do the conversion.
- Extruda — converts a plan to editable geometry and layered DXF/DWG, and keeps going into 3D (OBJ, glTF, .blend) and renders. Browser-based; free during early access.
- floor-plan.ai and similar AI web tools — fast image-to-plan conversion, with varying export options; check whether output is editable CAD or a visual.
- RoomSketcher (AI Convert) — converts and lets you redraw floor plans, oriented toward home-design and real-estate visuals.
2. Desktop raster-to-vector — most control
Installed software that vectorizes lines (and text via OCR) with granular manual control — best when CAD conversion is a big part of your work.
- Scan2CAD — a dedicated desktop raster-to-vector converter for DXF/DWG. See Extruda vs Scan2CAD.
- Raster2CAD and comparable desktop utilities — similar niche, offline.
3. Capture-first apps — when you must measure the space
If you don't have a plan yet and need to capture a physical property, these scan a space (often by phone) into a plan you can then export.
- CubiCasa — phone-scan to floor plan for real estate. See Extruda vs CubiCasa.
- magicplan — on-site capture and estimating. See Extruda vs magicplan.
4. Drafting services — guaranteed, hand-checked DWG
Human drafters redraw your plan into CAD to spec. Slower and pricier, but the output is verified — the safe route when accuracy is contractual. Turnaround is typically measured in days per plan.
How to choose
- You already have a plan and want speed → an AI web converter.
- CAD conversion is your daily work and you want control → a desktop raster-to-vector tool.
- You need to capture the actual space → a scanning app.
- The DWG must be guaranteed accurate → a drafting service.
- You also want 3D, renders, or other formats from the same plan → an AI converter that goes beyond CAD (see every export format).
Whichever route you take, make sure the output is editable geometry — layered DXF/DWG you can measure and modify — not an image that merely looks like a drawing. And for permitting or construction, base final drawings on surveyed measurements regardless of the tool.

What is the best tool to convert a floor plan to CAD?
It depends on your starting point. If you already have a plan as an image, PDF, or scan, an AI web converter (like Extruda) is fastest and needs no install. If you want granular desktop control over the vectorization, a tool like Scan2CAD fits. If you need to capture a physical space first, a scanning app like CubiCasa or magicplan is purpose-built. For guaranteed, hand-checked DWG, a drafting service is the safe route.
Can AI convert a floor plan to DWG?
Yes. AI detects the walls, rooms, and openings in a raster plan and turns them into editable vector geometry you export as layered DXF/DWG for AutoCAD or Revit. You correct anything it misreads in an editor before exporting.
Is there a free way to convert a floor plan to CAD?
Some tools offer free tiers or trials, and manual tracing in free CAD software is always an option (just slow). Extruda is free during its early access. Check each tool's current pricing, since free limits change.
Will I get editable CAD or just an image?
The point of converting to CAD is editable geometry — layered lines you can measure and modify — not a flat picture. Make sure the tool outputs DXF/DWG geometry rather than an image that merely looks like a drawing.
