Export your 3D model

Before you can drop a building into 3D Preview, you need it in a web-ready 3D format. Render a House accepts .glb (recommended), .gltf, and .obj. Native project files — SketchUp .skp, Revit .rvt — can't be uploaded directly, so the one step that matters is the export.

Which format?

• .glb — recommended. A single binary file with textures baked in. Nothing else to manage.
• .gltf — the same data as .glb but split across multiple files (separate textures / bin). Works, just more files to keep together.
• .obj — the classic interchange format. Use it as a fallback when your tool can't export glTF. Textures stored in separate files may not come across.

When you click Upload inside 3D Preview, the Import a 3D model dialog has step-by-step tabs for SketchUp and Revit. Pick your tool and follow along — the steps below are the same.

SketchUp

Modern SketchUp exports glTF natively — no extension to install.

1. Open your model in SketchUp.

2. Go to File → Export → 3D Model…

   

3. In the format dropdown, choose glTF Binary File (.glb).

   

4. Export the file, then drop it into the Upload file button in 3D Preview.

Older SketchUp versions without glTF export can't produce .glb directly — export .obj instead, or reach out via Chat with human in the app and support can help convert your .skp.

Revit

Revit doesn't export glTF on its own. Install the Leia – glTF Exporter plugin (by e-verse, for Revit 2021–2026) from the Autodesk App Store.

Once it's installed, open your model in Revit, run the glTF export, and save a .glb (or .gltf). Then upload it in 3D Preview just like any other model.

Rhino

• Rhino 7+ — File → Export…, choose glTF, and pick .glb to embed textures.
• Older Rhino needs the glTF-BinExporter plugin.

Blender

• File → Export → glTF 2.0 (.glb/.gltf).
• Choose the glTF Binary (.glb) format option so the textures travel inside the file.

Tips for a clean export

• Keep the model tidy. Delete anything you don't need before exporting — the cleaner the geometry, the cleaner the result. You can always add more objects inside 3D Preview later.
• Export at real-world scale. glTF's convention is 1 unit = 1 meter. If the model lands too big or too small on the map, use the Scale tool when positioning it.
• Watch the polygon count. Very dense meshes upload slowly — aim for under ~100k polygons (e.g. Blender's Decimate modifier) and prefer .glb over multi-file .gltf.
