Exporting a floor plan as a 3D model (GLB)

What the model contains

The model is written in metres with the usual Y-axis up, so it appears at real-world scale in any viewer. Doors and windows are genuine openings: the wall is split into bands around each opening rather than having a hole calculated into it.

Elements keep their meaning. Every node is named — a room with its name, a wall, a door with its width — and carries extra attributes, so downstream software can still tell a kitchen floor from a bathroom wall.

• Metric units, immediately to scale in any viewer
• Doors and windows as real openings, not painted-on symbols
• Named elements carrying per-element attributes
• Deliberately lean geometry so files stay small

Where the export pays off

In sales, a 3D model is strongest for properties that photograph badly: shell-and-core space, empty units, awkward layouts, or flats that are still occupied. Prospects see the structure without somebody else's furniture in the way.

In fit-out, the model is a starting point for visualisation. Because the geometry is clean and lean, it can be reused in a 3D package without first cleaning up millions of triangles.

Limits and expectation management

A GLB derived from a floor plan is a structural model, not an architectural rendering. It shows walls, openings, rooms and simplified furniture volumes — no real materials, no lighting mood, no skirting boards or ironmongery.

Say so up front. A prospect expecting a photorealistic image and receiving a structural model is disappointed; one who was promised a spatial diagram is impressed. The difference is entirely in the framing.
