GuideFloor plan to CAD, 3D & every export format
One floor plan can become a dozen different files — a layered CAD drawing, a 3D mesh, a vector, a printable model. The trick is picking the right format for the tool you're feeding. This guide maps every export, says which is native and which is a quick conversion, and links the step-by-step for each.
The short version
Match the format to where it's going:
| Format | Best for | From Extruda |
|---|---|---|
| DXF / DWG | CAD — AutoCAD, Revit, drafting | Native export |
| SVG | Vector line art, web, print | Native export |
| OBJ | Universal 3D mesh exchange | Native export |
| glTF / GLB | Web, AR, real-time 3D | Native export |
| .blend | Detailed editing in Blender | Native export |
| STL | 3D printing | One step from the 3D model |
| FBX | Game engines (Unreal, Unity) | One step from the 3D model |
The important distinction across all of them: you're exporting editable geometry, not a flat picture. The hard part — reading walls, rooms, and openings off the plan — happens once; the format is just how you carry that geometry into the next tool.
CAD formats: DXF & DWG
DXF and DWG are the backbone of professional drafting — layered, scaled, editable line geometry. They're what you want whenever the destination is AutoCAD, Revit, or any CAD workflow.
- PDF floor plan to DXF — turn a fixed PDF into editable CAD.
- Floor plan image (JPG/PNG) to CAD — from a raster picture to layered geometry.
- Get a floor plan into AutoCAD and convert a plan to Revit.
- DWG vs DXF — which of the two to use, and why.
3D mesh formats: OBJ, glTF/GLB, .blend, STL, FBX
Once the plan is a 3D model, the mesh formats are about where the model is going — a 3D app, the web, a game engine, or a printer.
- OBJ — the most universal mesh; opens almost anywhere.
- glTF / GLB — the "JPEG of 3D," ideal for web, AR, and real time.
- .blend — a native Blender scene for detailed editing and rendering.
- STL — for 3D printing a physical model of the plan.
- FBX — for Unreal, Unity, and game-ready 3D.
Vector: SVG
Sometimes you don't want 3D or CAD at all — you want clean, scalable line art of the plan for a website, a brochure, or a diagram. That's SVG: infinitely scalable, tiny, and styleable with CSS.
Which format should I use?
- Drafting / construction docs → DXF or DWG.
- Opening in a 3D app → OBJ (universal) or .blend (Blender).
- Web, AR, or a real-time viewer → glTF / GLB.
- Game engine → FBX (or glTF).
- 3D printing → STL.
- Flat vector graphic → SVG.

What formats can you export a floor plan to?
From one floor plan you can export CAD (DXF/DWG), 3D mesh (OBJ, glTF/GLB, .blend), and vector (SVG) directly. STL for 3D printing and FBX for game engines are a one-step conversion away from the 3D model. Which you pick depends on the tool you're feeding — AutoCAD/Revit want DXF/DWG, Blender wants .blend, the web and AR want glTF.
What's the best format for AutoCAD or Revit?
DXF or DWG. Both are the native CAD exchange formats — layered, scaled, editable line geometry that AutoCAD opens directly and Revit imports as an underlay or a basis for native elements.
What format do I need for 3D printing a floor plan?
STL is the standard 3D-print format. Export the plan as a 3D model (OBJ or .blend), make sure it's watertight, then convert to STL and send it to your slicer.
Can I get an editable file instead of just a picture?
Yes — that's the point of exporting to a real format. DXF/DWG give you editable CAD geometry, .blend gives you an editable 3D scene, and OBJ/glTF give you a mesh you can modify. None of these is a flat image; they're geometry you can measure, edit, and build on.
