How to export a floor plan to FBX

Updated 20 July 20264 min read

FBX is the workhorse interchange format for Unreal and Unity. If you're building an archviz walkthrough, a game level, or a VR scene from a real building, you want the layout as accurate geometry — and FBX is a quick hop from the 3D model of your plan.

The honest workflow

Extruda exports your plan as OBJ, glTF/GLB, and .blend. FBX is one conversion step from any of those — the geometry is identical, you're just repackaging it for the engine.

Upload your 2D floor plan (image, PDF, or scan).
Convert it to a 3D model and export OBJ or .blend.
In Blender, export FBX (or use a converter).
Import into Unreal or Unity and start dressing the scene.

FBX vs glTF for engines

FBX — the long-standing default for Unreal/Unity; strong for rigs and animation.
glTF / GLB — lighter, open, increasingly well supported (floor plan to glTF).

If your pipeline already runs on FBX, stay with it. If you're starting fresh, glTF is a fine modern alternative.

Getting to game-ready

The model gives you accurate walls, rooms, and openings at real scale — you skip blocking out the layout by hand. In-engine you'll still add materials, lighting, collision, and optimization. For that side, see floor plans to game-ready 3D, and for the full list of outputs, every export format.

Frequently asked questions

How do I export a floor plan to FBX?

Convert the 2D plan into a 3D model, export it as OBJ, glTF, or .blend, then convert to FBX in Blender or a converter. FBX is the standard interchange format for Unreal and Unity, so it's a quick last step once you have the model.

Does Extruda export FBX directly?

Extruda exports OBJ, glTF/GLB, and .blend. FBX is one conversion step from any of those — the geometry is identical, you're just repackaging it for a game engine. We do the hard part of turning the plan into accurate 3D.

FBX or glTF for a game engine?

Both work. FBX is the long-standing default for Unreal and Unity pipelines and handles rigs and animation well. glTF is lighter and increasingly supported. If your team already uses FBX, stay with it; otherwise glTF is a fine modern choice.

Is the floor plan model game-ready as-is?

It gives you accurate building geometry to start from — walls, rooms, and openings at real scale. For a shipping game you'll still add materials, lighting, collision, and optimization in-engine, but you skip blocking out the layout by hand.
