Exporting a 3D model (GLB)
Need your room in another 3D tool? Export the whole scene as a standard GLB file.
Export your design as a GLB — the binary glTF format for AR viewers, Blender, SketchUp, Unity, and many other 3D tools.
Step by step
- 1
Open the GLB export
Top bar → Share / Export → Export to GLB. The Export as 3D model dialog opens.
Export as GLB — a full 3D scene for AR, Blender, SketchUp, or the web. - 2
What you get
A .glb file containing the full 3D scene — walls, doors, windows, stairs, and furniture, the same geometry the 3D view renders. It's AR-ready (iOS Quick Look, Android Scene Viewer) and opens in Blender, SketchUp, three.js, and Babylon.js.

Export
Click Export GLB. Building the model takes one to three seconds on a furnished plan; the file then downloads. Size is typically 5–50 MB depending on furniture count.
Tips
Open in any glTF viewer
Blender, Three.js, A-Frame, Babylon.js, Unity, Unreal, Apple AR Quick Look — all accept GLB. Drag into a glTF viewer to inspect.
Common mistakes
Expecting GLB to re-import
GLB is a 3D model for viewers and 3D tools, not an editable RoomSketch3D design. To move a design between accounts, export JSON instead.
Looking for GLB on iOS
GLB export is web-only. Export it from the web app; the file then opens in AR and 3D tools on any device.
Frequently asked questions
Can I open a GLB in Blender or SketchUp?
Yes. Blender imports glTF natively. SketchUp supports it through a plugin.
Why is GLB disabled in the mobile app?
Native file write requires a bridge to the OS that isn't enabled on iOS/Android yet. Use the web version to export GLB.
Can I open a GLB on my phone?
Yes — GLB opens in AR viewers on iOS and Android, and in 3D tools like Blender and SketchUp. Export it from the web app first.
Is a GLB editable back in RoomSketch3D?
No — GLB is a model for viewing and 3D tools. To move an editable design between accounts, export JSON instead.
