Supply-air starter branch

Supply-air starter branch is an M1 showcase built from real Harth library objects: 6 parameterised instances of 6 distinct objects, with 5 authored joints recorded between their connectors. The background is authored geometry — a 7 × 6 m inspection floor with context massing, a north point and a 1.7 m scale figure — so every services item in the scene is a live, editable library instance rather than fixed mesh.

Open it and the services objects keep their parameters and connector metadata, so the agent can inspect, check and correct them. 6 connectors are deliberately left open.

Real library geometry and parameters are retained. GLB and IFC are static inspection mirrors; use the placement package to create editable Harth library instances.

No routing solver or persisted connection graph is claimed. The documented port pairs are authored joints, and every unused port is listed.

Nominal design geometry; no engineering rating, code compliance, horticultural suitability or cadastral accuracy is claimed.

Try these prompts with the agent:

Inspect the five recorded port pairs from the AHU to the ceiling diffuser. Report position, flow and profile compatibility.

Can this 200 mm supply duct join a 250 mm neck? Explain the reducer needed before placing anything.

Replace the straight duct with a 1 m, 200 mm supply duct, then reposition downstream parts and recheck the recorded joints.

List the unused AHU ports and explain why this branch is not a complete ventilation system.
