# cao_regles_structure_reseaux

WHEN a building scene must be completed with structure and building services by French rules before BIM export or quoting: lintels over openings of load-bearing walls, strip footings sized from service loads, slab span check (indicative pre-design, to be validated by a structural engineer); NF C 15-100 electrical points per room (outlets, RJ45, lighting with its switch, one smoke detector per level, panel with 30 mA RCD) and circuit count; single-flow mechanical ventilation per the 24 March 1982 decree (extract grilles in wet rooms, air inlets in dry rooms, fan, flows); drainage branches with slopes per NF DTU 60.11; water inlet and 200 L water heater placed where missing; room heat losses per NF EN 12831 and radiators sized at 55/45 °C (NF EN 442). Adds what is missing, never removes. Returns {scene, rapport, controles}; send scene to cao_generer_ifc to get IfcBeam, IfcFooting, IfcOutlet, IfcAirTerminal, IfcPipeSegment, IfcSpaceHeater…

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `sol` | object | no | Soil assumptions for footings: {contrainte_mpa (default 0.20), hors_gel_mm (default 800)}. |
| `vmc` | boolean | no | Generate single-flow ventilation (extract grilles, air inlets, fan, flows). |
| `murs` | array | no | Walls: plan segments extruded vertically. Every coordinate in this whole scene is in MILLIMETRES, in a single plan frame whose origin you choose — X to the righ |
| `plan` | array | no | 2D reference lines — drawn flat, never extruded and never counted in the quantities. Use them for axes, plot limits or setting-out marks. |
| `boites` | array | no | Boxes (furniture, volumes): a rectangular block placed by its CENTRE, not by a corner. Millimetres, same frame as murs[]. |
| `georef` | object | no | Optional Lambert-93 (EPSG:2154) false origin for IfcMapConversion. Local millimetres are scaled by 0.001 to CRS metres. Do not invent coordinates: omit est/nord |
| `cercles` | array | no | Circles on the 2D plan, alongside plan[] lines: each has a centre and a radius, in the same unit as the plan. Use for round shapes a polyline would render badly |
| `reseaux` | array | no | Plumbing pipe runs (EF/EC/EU/EV/EP/chauffage) — used only by cao_pdf (technical plan + linear-meter quantities per type). |
| `toitures` | array | no | Roofs — used only by cao_pdf. WITHOUT this field: a flat roof is auto-generated over the footprint of ALL walls (legacy default). WITH it: compose freely — each |
| `chauffage` | boolean | no | Compute room heat losses (NF EN 12831) and size radiators at 55/45 °C. |
| `plomberie` | array | no | Sanitary fixtures (sink, WC, shower…) — used only by cao_pdf. Same positioning as electricite. |
| `structure` | boolean | no | Generate lintels and strip footings, check slab spans. |
