How 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

  1. Upload your 2D floor plan (image, PDF, or scan).
  2. Convert it to a 3D model — the 2D-to-3D step.
  3. Export OBJ (it comes with a companion .mtl for basic materials).
  4. Open it in Blender, Cinema 4D, 3ds Max, a game engine, or any 3D app.

Frequently asked questions

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.
