Live AR needs a WebXR-AR capable phone (recent Android Chrome, or a headset browser). It places the real model on a detected ground plane at true scale; the HUD reads your GPS location and the project's real figures. On unsupported devices, use Site Composite instead β it works everywhere.
π¦ EXPORT AS AR FILE β place your stadium in real space on a phone
The AR Launch Page is the easy button: it embeds both files and a "View in your space" control, so it just works whether the phone is iPhone or Android. GLB and USDZ are the raw files if you want to use them directly or in another tool.
The overlay uses the live model's real capacity, height, footprint and cost. Distance is computed from your tagged GPS to the site if both are set; otherwise it's hidden rather than guessed.

Multi-objective frontier β sweeps the design space (tiers Γ rows Γ rake) and evaluates each candidate on cost, embodied carbon, capacity and sightline with the real engines, then extracts the Pareto-optimal (non-dominated) trade-off set. Pick by preference instead of one baked-in weighting.
π² Geometric Uncertainty
