GuideHow to convert a floor plan to OBJ
OBJ is one of the most universal 3D formats — almost every 3D tool reads it. If you want a floor plan as a simple, portable 3D mesh you can open anywhere, exporting OBJ is a safe bet. The route is the usual one: turn the 2D plan into a 3D model, then export OBJ.
The workflow
- Upload your 2D floor plan (image, PDF, or scan).
- Convert it to a 3D model — the 2D-to-3D step.
- Export OBJ (it comes with a companion .mtl for basic materials).
- Open it in Blender, Cinema 4D, 3ds Max, a game engine, or any 3D app.
OBJ vs glTF vs .blend
- OBJ — simplest, most universal; great for plain geometry exchange (see what is an OBJ file).
- glTF / GLB — better for the web, AR, real time, and richer materials (floor plan to glTF).
- .blend — native Blender scene for detailed editing (floor plan to Blender).
Export your plan as OBJ
Upload a 2D plan and get a universal OBJ model — plus glTF, .blend, CAD files, and renders.

Can you convert a floor plan to an OBJ file?
Yes. Convert the 2D plan into a 3D model, then export OBJ. The file opens in almost any 3D tool — Blender, Cinema 4D, 3ds Max, game engines, and more.
OBJ or glTF — which should I use?
Use OBJ for simple, universal exchange between 3D tools. Use glTF/GLB when you need the web, AR, real time, or richer materials and animation. Many pipelines keep both around.
Does an OBJ file include materials?
OBJ stores geometry and references materials through a companion .mtl file. It carries basic material data, but less than glTF, so complex materials may need setup in your 3D app.
Do I need 3D software to make the OBJ?
No. An AI tool like Extruda produces the OBJ in the browser from your 2D plan; you only need 3D software to open and work with it.
