3D models for interior design

Interior designers need furniture and decor in 3D for two jobs: planning (does it fit, does it flow) and selling (does the client love it). The first needs accurate dimensions. The second needs good materials.

Planning with real-world scale

Before trusting any model in a layout, check its dimensions against the real piece. A typical dining chair seat is around 45 cm high and a sofa seat around 40–45 cm. Resize the model in Blender or SketchUp so it matches the spec sheet.

Making a piece that isn't in any library

Clients often fall for a vintage find or a one-off piece that no model library has. Photograph it at a three-quarter angle on a plain background and run it through image to 3D. The result is good enough to test placement and colour, which is what a concept board needs.

Materials sell the room

Velvet, brass, walnut and linen are what clients respond to. The PBR materials in models like the velvet armchair and floor globe respond properly to light, so a render reads as a real room, not a diagram.

AR previews

Exporting a piece as GLB and USDZ lets a client open it on their phone and place it in their own room. It's a quick, convincing way to settle the "will it be too big?" question. See our notes on AR formats.
