ComparisonExtruda vs Scan2CAD
Both convert a raster floor plan into CAD — but in different environments. Scan2CAD is a desktop app built for raster-to-vector conversion with fine manual control. Extruda is a browser AI tool that converts a plan to editable geometry and then keeps going — into 3D models, furnished renders, and multiple export formats. Want deep desktop CAD-cleanup control? Scan2CAD. Want fast, self-serve conversion that also unlocks 3D? Extruda.
What Scan2CAD is best at
Scan2CAD is a dedicated raster-to-vector converter: load an image or PDF, and it vectorizes lines (and text, via OCR) into DXF/DWG you refine on the desktop. If your work is CAD-conversion-heavy and you want granular control over how strokes become vectors — with an installed, offline tool — that's its strength.
What Extruda is best at
Extruda detects walls, rooms, and openings from a plan with AI and turns them into editable geometry in the browser — this is vectorization too, but self-serve and AI-driven. From that single model it also produces a 3D model, renders, and many export formats beyond CAD. No install, no CAD license to do the conversion.
Side by side
| Scan2CAD | Extruda | |
|---|---|---|
| Environment | Installed desktop app | Browser — nothing to install |
| Core job | Raster-to-vector for CAD | Plan → editable geometry, CAD, 3D |
| Detection | Vectorization + OCR, manual control | AI detection of walls/rooms/openings |
| CAD (DXF/DWG) | Core focus | Yes — layered export |
| 3D & renders | Not the focus | Yes — OBJ/glTF/.blend + renders |
| CAD license needed? | Uses its own app | No — convert & edit in-browser |
Which should you choose?
- You do a lot of CAD conversion and want desktop control → Scan2CAD.
- You want fast, self-serve conversion with no install → Extruda.
- You need more than CAD — 3D, renders, glTF/OBJ/.blend from the same plan → Extruda.

Is Extruda a Scan2CAD alternative?
For converting a raster floor plan to CAD, yes — they overlap. Scan2CAD is a desktop application focused on raster-to-vector conversion (images/PDFs to DXF/DWG) with fine manual control. Extruda is a browser-based AI tool that converts a plan to editable geometry and also goes further — into 3D models, furnished renders, and multiple export formats. If you want deep desktop CAD-cleanup control, Scan2CAD fits; if you want fast, self-serve conversion that also unlocks 3D, Extruda fits.
Does Extruda do raster-to-vector like Scan2CAD?
Yes — detecting walls, rooms, and openings from a raster image and turning them into editable vector geometry is exactly what Extruda does (vectorization). The difference is Extruda runs in the browser with AI detection and then continues to 3D and other outputs, whereas Scan2CAD is a dedicated desktop CAD-conversion tool.
Desktop app or browser?
Scan2CAD is installed desktop software. Extruda runs in the browser — nothing to install, and no CAD license needed to do the conversion and editing. You only need CAD software afterward if you want to keep working on the exported DXF/DWG.
Which is better if I only need DXF/DWG?
If your only goal is precise raster-to-vector CAD conversion and you want granular desktop control, Scan2CAD is built for that. If you want a quick DXF/DWG plus the option of 3D, renders, and other formats from the same plan, Extruda covers more ground.
