read_ifc_overview CALL THIS FIRST, as soon as the user gives you a token. It answers within seconds, while the network graph is still being built - use that time to think. THE CIRCUITS OF A MODEL IN FOUR CALLS: 1. read_ifc_overview - this call: the types of the model. 2. apply_ifc_rules - your rules. Give air ha
apply_ifc_rules Turn what you read in the overview into rules the tool replays on EVERY piece of the model, including the ones you were never shown. THIS IS HOW THE TOOL LEARNS A MODEL. read_ifc_overview gives you some fifty groups — one per object type, not one per piece. You answer with RULES on those groups, an
read_ifc_networks DETERMINISTIC: networks come from geometry, not from a guess. The same model always gives the same networks, from any AI, on any day. Read the networks of an IFC model already uploaded by the user. WHAT A NETWORK IS. A set of parts that touch each other, cut at equipment: a pump, an air handling u
name_ifc_networks Apply the names you propose, and get back the updated report. THE NAMES ARE YOURS, THE NETWORKS ARE NOT. You are naming what the tool measured; you are not changing what it measured. Nothing you send here alters a network, a part, or a correction. WHAT COMES BACK. The updated report, a 3D link whe
trace_duct_circuits THE CIRCUITS THE FANS OF A MODEL ARE SIZED ON, found without anyone clicking and computed on the pressure-drop page, where the user confirms types and flows and reads the pressure drops. ONLY UNITS AND FANS ARE EXCHANGED. The tool never sends you system names: it sends the air handling units and fa
open_ifc_upload Show an upload box in the conversation where the user can drop an IFC file (.ifc) of a building services model (HVAC, plumbing, heating). The file goes straight from the user's browser to thenewengineer.com - you never see it. CALL THIS when the user wants to analyse an IFC model and has not yet gi
ifc_upload_result Where the upload stands. When `state` is `depose`, `token` is the token to pass to read_ifc_networks.
