QUAND un candidat constitue son dossier pour un logement. Dossier de CANDIDATURE locataire (HTML ; PDF via /api/v1/documents/candidature). Destinataire fenêtre = agence. À classer dans le dossier local après réception.

WHEN the building must be shown AS IT WILL BE BUILT over time (4D, as Navisworks links a model to a schedule): every element belongs to a trade (load-bearing walls to structural works, roof to roofing, facade openings to exterior joinery, partitions and rooms to drywall, interior doors and stairs to interior joinery, finishes, furniture at handover); the schedule comes from the model's quantities. Returns one step per trade with its dates and, as SVG, the axonometric view and the ground-floor plan as built at the end of that trade, and optionally the state at a given date.

WHEN clashes and control alerts must leave as a BCF 2.1 zip readable in Solibri, BIMcollab, Navisworks, Revit or Archicad: one Clash topic per clash and one Issue topic per alert of our checks, each selecting its objects by IFC GlobalId with a camera in front of them. Pass a scene or `ifc` (an architect's IFC text). Returns {topics, conflits, alertes, bcf_base64}: write bcf_base64 to a .bcfzip file.

WHEN a parametric family (custom shelf, window, bench…) must be reused across projects or shared: the account's family library, like Revit's family library. action=lister: your families then the public ones of others (anonymous author code); action=lire: one family, ready to copy into scene.familles (with its origin); action=enregistrer: save a new version of `famille` under `nom` (unchanged definition: no new version), `publique` to share it. Build and test the family first with cao_famille_essayer.

WHEN a house design must be ISSUED as a drawing set (a Revit-style sheet set), for a client, a planning application or a contractor. Builds numbered A3 or A1 sheets: cover with sheet list, site plan, one plan per storey, elevations, section, MEP plans per storey and schedules. Views are printed at TRUE SCALE (1:50, 1:100, 1:200... the largest standard scale that fits, never a false one). Every sheet carries a title block (project, client, phase, sheet code and title, scale, revision, n/N), the revision table and an 8-character fingerprint of the model it came from. Returns JSON {feuilles:[{code, titre, echelle}], empreinte, html}: the html prints one page per sheet.

WHEN two versions of a house design must be compared: what the client, the architect or another agent changed, and what it changes to the quantities (the basis of a change order). Elements are matched by geometry (wall end points, wall and position of an opening, type and position of an object), never by their index, so deleting one wall does not report every following wall as modified. Returns added, removed and modified elements field by field, and the quantity take-off difference item by item.

WHEN coordinating a BIM model: detect real clashes — solids that interpenetrate by more than 10 mm and 0.1 L, computed on volumes (horizontal slices of each mesh), so two tables nested at the same level are caught and a bed standing against a wall is not. Pass a scene (same as cao_generer_ifc) or `ifc`: the text of an architect's IFC, whose GlobalIds are kept. Wall-slab bearings, wall corner/T joints, objects standing on a rug or deck and doors in their wall are intended geometry, counted in `ignores`. Returns {conflits, ignores, elements, boite_modele}.

WHEN a user asks to change an existing building scene in plain words — « agrandis la cuisine d'un mètre », « réduis la chambre 2 de 50 cm côté nord », move a wall, widen a door, move or rotate furniture: the request becomes typed operations (catalogue: GET /api/v1/cao/copilote), executed to the millimetre (attached walls extended, furniture against the wall follows it, objects in the way pushed, switches moved out of door openings), then the result is re-checked by our controls. A wall that would create a defect is not used; a load-bearing wall stacked with another storey never moves alone. Returns {compris, source, operations, journal, erreurs, nouvelles_alertes, valide, scene, difference}; send `scene` on to cao_generer_ifc or cao_pdf.

WHEN you are about to draw ANY French building for the first time, or when a user asks for a plan / DXF / IFC and you have not yet used these tools — call this FIRST. It hands back a COMPLETE, ALREADY-VERIFIED scene (zero audit alerts) plus the exact next calls in order. FREE, no API key, 0 units. WHY IT MATTERS: composing a scene from the schema alone takes several round-trips and usually fails on the same mistakes (openings.z used as an absolute altitude instead of a relative sill, a storey with no windows). Starting from a working scene and editing it is faster and cannot fail. GOOD CALL: cao_demo {} -> the house; cao_demo {"exemple": "appartement"} for a flat with no roof; cao_demo {"exemple": "extension"} for a veranda grafted onto an existing facade. Then feed `scene` straight into cao_verifier, then cao_pdf / cao_generer_dxf / cao_generer_ifc. DO NOT: do not invent a scene from scratch before trying this; do not call it to CHECK a scene you already have (that is cao_verifier); do not expect a drawing back — this returns JSON, the drawing comes from the next call. All dimensions are MILLIMETRES.

WHEN a client or a contractor needs the QUANTITIES to price a house, trade by trade — the skeleton of a French DPGF. From the CAO scene, completed by the rules if needed: structural works (footings and lintels from the structure, ground slab, floors, load-bearing walls by thickness, gables), roofing, windows and doors by size, partitions, linings and ceilings, electrical points by type and cable length by cross-section, plumbing, heating and ventilation (radiators, heat pump, pipes, vents, ducts), floors and paint. No price is ever invented: pass your own unit prices in `prix` (and tva_pct) to get totals; items left without a price are listed in sans_prix.

WHEN you need the drawing-set completeness check alone: one plan per level, every upper floor reached by a staircase that actually arrives there (or a lift), stairwells protected by guardrails (NF P01-012). Returns alerts, applicable `correctifs` and the coverage per level. Free, no key. cao_verifier already includes it.

WHEN someone asks what a house will COST TO RUN, what it costs the climate, or whether it will overheat in summer. From the CAO scene: the heating need by the degree-day method (envelope and ventilation heat-loss coefficients, solar gains per orientation corrected by shading factors MEASURED on the scene's own sun paths, internal gains, and the EN ISO 13790 gain-utilisation factor), domestic hot water, and the resulting consumption in final and primary energy for the chosen generator; an order-of-magnitude embodied carbon figure (Ic construction) from the bill of quantities times YOUR emission factors; and a summer check comparing August solar gains against what one night of ventilation can remove. Climate data (degree-days, irradiation) and carbon factors come from the caller — nothing is guessed. This is NOT a French DPE nor the regulatory RE 2020 calculation.

WHEN a custom parametric object is needed that no catalogue has (a made-to-measure shelf, a counter, a pergola, a technical box): try a family DEFINED AS DATA, like a Revit family — typed and bounded parameters, derived formulas, constraints, and solids whose dimensions are expressions (arithmetic, comparisons, min/max/round, a if c else b; nothing else is evaluated). Returns the computed values, constraint findings and solids in mm. To place it, add the definition under `familles` and instances under `instances` in any CAO scene: they become boxes in plans, 3D and quantities, and typed IFC objects with their parameters.

WHEN you place doors or windows in a scene and want real, orderable joinery instead of free-size holes: lists the parametric families (hinged door in the French 63/73/83/93 series, double, sliding, pocket and entrance doors, French window, sliding patio door; one- or two-leaf, tilt-and-turn and fixed windows) with bounded parameters and the bay size each gives. An `ouvertures[]` entry declaring `famille` + `parametres` is checked (out-of-series values refused, accessibility per the French 24 December 2015 decree) and exported to IFC as a door/window type with shared geometry, lining and panels. Free, no key.

WHEN a scene uses families placed from the library and the library has newer versions: reload them (Revit's Reload Family). Each family with an `origine` moves to its latest version, unless that version would reject instances already placed (reported, the old version is kept). Returns the updated scene and what was reloaded.

WHEN a house design needs its STRUCTURAL pre-design: the load path of every load-bearing wall (dead and live loads separated, SLS and ULS combinations, soil pressure against the allowable value) and simplified reinforcement per Eurocode 2 (C25/30 concrete, B500 steel) for strip footings (strut-and-tie), lintels and slabs, as bars (for example 3 HA12, HA10 every 15 cm) and kilograms of steel. Slabs too thin for their span are flagged instead of being over-reinforced. A pre-design for costing, to be validated by a structural engineer.

WHEN two people or agents changed the same house design in parallel, starting from the same version, and both changes must be kept (like synchronising with a Revit central model). Three-way merge, element by element and field by field: a change made on one side goes through; the same field changed differently on both sides, or an element deleted on one side and modified on the other, is returned as a conflict, never silently overwritten. An opening stays on its own wall even if the other side deleted a wall before it. Pass `resolutions` {conflict id: central | local} to settle conflicts. Elements keep a persistent identity (ifc_guid, equal to their IFC GlobalId, or your own external_id). Pass `empreinte_base` (SHA-256 of the base you loaded) to refuse a merge on another base; the answer gives the SHA-256 of the three versions and of the result.

WHEN the drawing must leave as a real CAD file, openable by an architect or a draughtsman. Draw a building scene and get an AutoCAD DXF. Call cao_verifier first to catch geometry mistakes. Scene schema: GET https://synergieloc.fr/api/v1/cao/schema. Returns a JSON object {dxf, faces, entites_2d, unites, note}: the whole DXF drawing arrives INLINE as text in `dxf` — there is no download URL and no file stored on the server, so write it to a .dxf file yourself. `faces` and `entites_2d` count what was produced, `unites` states the drawing unit. alertes[] lists geometry issues still standing. Choose cao_generer_ifc instead when the recipient needs BIM objects rather than lines.

WHEN the drawing must leave as a real BIM file, openable in Revit/ArchiCAD/Solibri — not just a drawing. Draw a building scene and get an IFC4 file in millimetres: real spatial hierarchy (project/site/building/storeys), STABLE IFC GlobalIds (the same model keeps them across exports; pass projet_id; imported elements keep theirs), structural columns and beams (`poteaux[]`, `poutres[]` become IfcColumn, IfcBeam; see GET /cao/schema), one named IfcSpace per room with its areas (floor, French habitable and Carrez), floor slabs cut by their stair openings, an IfcRoof, IfcStair flights, standard Pset/Qto quantities, and material layers carrying density and thermal conductivity. Wall/slab/door/window types, 2nd-level space boundaries, and Lambert-93 georeferencing (EPSG:2154, Scale 0.001) are included so Revit/Archicad can open a typed, located model. Declare compositions{} to replace type compositions. Doors/windows really cut their host wall (IfcOpeningElement + IfcRelFillsElement). Passes IFC4 schema and EXPRESS-rule validation. Validate locally with cao_valider_ifc (no buildingSMART account). Call cao_verifier first. Same scene as cao_generer_dxf. Returns a JSON object {ifc, elements, unites, schema}: the IFC file arrives INLINE as text in `ifc` — no download URL, nothing stored server-side, so write it to a .ifc file yourself. `elements` counts the IFC objects emitted and `schema` names the IFC version produced. Set `armatures: true` to add the reinforcement: IfcReinforcingBar with exact geometry for footings and lintels (aggregated to their host), one IfcReinforcingMesh per slab.

WHEN a BIM manager's information requirements (an IDS 1.0 file, buildingSMART) must be checked on a model before delivery — ours built from the scene, or an architect's IFC: checks every specification (entity, attribute, property compared in SI units, classification, material, partOf; required, optional, prohibited; target IFC version) and returns, per specification, the applicable elements and those failing with their reasons; `bcf: true` adds the failures as BCF 2.1 topics with their objects. Without `ids`, checks our French housing IDS (rooms with net, habitable and Carrez areas, typed doors and windows, accessibility, load-bearing walls with materials, storeys, stairs, Lambert-93), free at GET /api/v1/cao/ifc/ids/logement-fr.

WHEN an architect sends an IFC (Revit, Archicad… IFC2X3 or IFC4) and you must check it with our rules: converts the IFC text into a CAO scene — walls, doors and windows on their host wall, straight stair flights, railings, named rooms, furniture, roof — each element keeping its GlobalId (ifc_guid). Returns {scene, rapport, controles, metres}: controles = the cao_verifier audit, metres = quantities; conflits:true adds clashes, studio:true opens the 4K video studio and the VR tour of the imported model. Reuse `scene` with every other cao_* tool.

WHEN you need the structural-integrity check alone (is the building really closed and roofed? walls that join nothing, wall clusters scattered outside the envelope, open roof, walls or volumes in each other, stairs badly placed). Returns alerts, applicable `correctifs` (field → value) and, with appliquer: true, the corrected scene. Free, no key. cao_verifier already includes it.

WHEN the deliverables of a project must be produced for real (IFC, DXF, drawing sheet, quantities, schedules). Runs the checks FIRST (those of cao_verifier); if any alert is critical, NOTHING is produced and exports_authorized is false. Otherwise produces the deliverables, validates the IFC (IFC 4 schema, buildingSMART rules; an IDS you provide must pass) and returns a manifest: SHA-256 of the scene (sorted JSON, compact separators — compare it with your own), SHA-256 and size of every deliverable, checks run, version, author, date. An unexplained warning forbids a PROFESSIONAL delivery (exports_professionnels_autorises) — explain it in warnings_expliques. professional_review_required lists what remains a pre-study.

WHEN you need FIGURES from a design — to price a job, order materials, or check a quote. Compute quantities (metrés) from a CAO scene. Also returns alertes[] from the geometry audit — fix critical alerts before quoting. Same scene as cao_generer_dxf.

WHEN you are about to furnish or decorate a scene — call this BEFORE composing `mobilier[]`, and never furnish with `boites[]`. FREE catalogue (no API key, 0 units) of REAL furniture and decoration objects. Until now a scene could only hold `boites[]` — bare cuboids — so an « fully furnished » house came back as grey cubes; this is the vocabulary that fixes it. ~50 modelled articles: OUTDOOR (parasol with mast/canopy/base, garden table+chairs set, sun lounger, barbecue, pergola, planter, gate, wrought-iron / wire-mesh / timber fencing, hedge, deciduous & conifer trees, garden shed, bench, pool), BATHROOM (wc, washbasin, shower, bathtub), KITCHEN (sink, fridge, oven, hob, extractor hood, fitted kitchen), LIVING/BEDROOM (sofa, corner sofa, armchair, coffee table, rug, bookcase with books, indoor plant, TV, floor lamp, mirror, framed art, curtains, bed, wardrobe, chest of drawers, bedside table). Each returns {categorie, libelle, cotes_defaut} — dimensions are OPTIONAL, defaults are real commercial sizes (3-seat sofa 2100×950, double bed 2000×1600, parasol Ø3000). Place with {type, x, y, z, rotation} where z is the FLOOR level under the object, not its centre. They appear in the 4K visit, the PDF board, the DXF and the quantities. Plumbing fixtures declared in `plomberie[]` are now also placed in 3D — do not duplicate them here. REST: GET /api/v1/cao/mobilier.

WHEN someone needs the SCHEDULES of a house design, as Revit calls them: the door and window schedule (one mark per type, P1 for doors and F1 for windows, with size, sill height, leaves, clear opening width, accessibility and the count per storey, then every opening with the rooms on each side), the room schedule (floor, habitable and Carrez areas, perimeter, ceiling height and volume, with totals per storey and for the building) and the equipment schedule (sanitary, electrical, heating, ventilation and furniture counts per storey). The figures match the IFC export exactly: same spaces, same door and window types, same IsExternal flag.

WHEN the design must be HANDED OVER to a client, an architect or a planning office. Generate a professional TECHNICAL SHEET from a CAO scene: top view, elevations, shaded axonometric, optional MEP plan. IMPORTANT: call cao_verifier FIRST and fix critical alerts (floating dormers, absolute sill heights, upper floor without windows) before delivering — the sheet embeds an orange alert banner when issues remain. Returns JSON {html, alertes, alertes_ok, resume}. Same scene as cao_generer_dxf.

WHEN a detached house is headed for a French BUILDING PERMIT (permis de construire, Cerfa 13406). Drafts the permit file from the CAO scene: the Cerfa figures (surface de plancher per R111-22 — inner face of façades, stair openings and parts under 1.80 m excluded; emprise au sol per R420-1; eaves and ridge heights; storeys), plus PCMI2 site plan, PCMI3 section, PCMI4 written notice and PCMI5 elevations. PCMI1, PCMI6, PCMI7 and PCMI8 (location map, landscape insertion, photos) are listed as 'à fournir' — never invented; a Géoportail link is given when the scene has `georef`. For an EXTENSION, mark the existing walls `existant: true`: existing and created areas are then separated, and the file says when a déclaration préalable is enough (up to 20 m² created, 40 m² in a PLU urban zone). Local zoning rules (PLU) are NOT checked. Call cao_verifier first. Returns JSON {cerfa, pieces[], notice[], alertes[], avertissement}; drawings are SVG strings.

WHEN you are asked to DESIGN a house from a brief ('3 bedrooms, open kitchen, 90 m²') rather than to check or edit an existing scene. Returns a complete single-storey house scene — walls, doors, windows, named rooms, roof — laid out to French dimensions (1.00 m corridor, 90 cm doors, bedrooms of 9 m² and more, 1/6 glazing in living rooms, load-bearing walls keeping every slab span under 5.60 m) that passes cao_verifier with zero alerts, with its rooms and areas, and the other layout type as a variant. Two layouts: 'aile' (through living room and a night wing on a central corridor) and 'bandes' (day strip, corridor, night strip). Single-storey only for now. Then: cao_copilote to retouch, cao_verifier after any edit, cao_generer_ifc or cao_permis.

WHEN a house design needs an early THERMAL sanity check before the regulatory RE 2020 study (French energy and carbon rules for new buildings). Computes from the CAO scene: envelope areas and U-values, H_T in W/K with 10 % thermal bridges, mean U, compactness, which walls, roof or floor lose most, ventilation losses at the dwelling's base airflow, glazing per orientation, heat loss at design temperature, and design levers. It NEVER outputs a Bbio, Cep, DH or Ic figure: those need the official Th-BCE engine and a life-cycle assessment by a thermal consultant; the RE 2020 thresholds for houses are recalled with their sources.

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…

WHEN you want to SEE the plan before delivering it — a quick visual check that the scene is what you meant. Top-down preview of a CAO scene. Prefer cao_verifier before this for structured alerts; use the preview to visually double-check. Returns the picture itself, never a link: format=svg gives SVG markup as text, format=png gives an MCP image you can look at directly. Read-only — nothing is drawn, saved or sent anywhere.

WHEN a design must be reviewed trade by trade (building envelope and load-bearing walls, openings, floors and roofs, stairs and guardrails, electrical, plumbing, ventilation, furniture and circulation). Runs the checks of cao_verifier and sorts every alert into the trade of the elements it names, with those elements (external_id, else ifc_guid), the proposed fixes, what is missing, and professional_review_required where our checks do not calculate (structure, floors, roofs). A pre-study, never a compliance statement. Free, no key.

WHEN a design decision depends on the SUN: how many hours of direct sunlight each window actually receives, where the building casts its shadow on the plot, and whether a neighbouring building or screen blocks the light. From the CAO scene, for the three dates that decide a project (21 June, 21 March, 21 December): sunrise, sunset, maximum altitude, the shadow at solar noon (area and outline), and per window the hours of sun with the first and last hour, its orientation and its azimuth. Obstacles are the building's own walls and roof plus any `masques` you declare. The site comes from `georef` (Lambert-93); without it Strasbourg is used and the answer says so. No solar gain in watts and no RE 2020 discomfort hours: those need a dynamic thermal engine.

WHEN a design must be checked against the LOCAL PLANNING RULES of its zone (French PLU) before a building-permit application. Measures on the CAO scene: site area, footprint and its percentage, floor area, eaves and ridge heights, the setback of EVERY plot boundary with the building height facing it, roof pitches, parking spaces, open ground; then checks them against the rules YOU pass in `regles` (recul_voie_m, recul_limites_m, prospect_h_sur_2, emprise_max_pct, hauteur_max_m, hauteur_max_faitage_m, pente_toit_min_deg, pente_toit_max_deg, stationnement_min, espaces_verts_min_pct). Each check returns the value, the threshold, whether it passes and what to change. NO planning value is ever invented: read the zone's regulation (Géoportail de l'urbanisme) and pass it. Without rules, the measurements alone are returned.

WHEN you need to check an IFC scene without a buildingSMART account. Same scene as cao_generer_ifc. Returns {ok, schema_ifc4, regles, problemes}: IFC4 schema + EXPRESS rules, millimetre units, material layers on every IfcWall, named IfcSpace, thermal conductivity in Pset_MaterialThermal, every element in a storey.

WHEN a scene is composed and BEFORE cao_pdf / cao_generer_dxf / cao_rendu / cao_visite_plan / cao_visite_studio — the cheap check that stops a wrong plan or broken 4K visit from being delivered. FREE geometric audit of a CAO scene (no API key, 0 units). Detects the mistakes that make planches look wrong: openings.z used as absolute altitude instead of relative sill (allège), chien_assis dormers floating outside the roof, upper storey walls with no windows, guardrails far from the building, missing stairs between floors, openings overflowing their wall. ALSO checks that a staircase actually leads somewhere (escalier_traverse_mur — the flight runs into a partition of its own level; escalier_arrivee_hors_batiment — it lands outside the walls). STAIRCASE PLACEMENT is checked in full, because a stair dropped in an absurd spot is the most visible flaw of an AI-composed model: escalier_depart_hors_batiment (it starts in the void), escalier_volee_hors_batiment (the flight leaves the building on the way up), escalier_bloque_ouverture (it seals a doorway), escalier_z_hors_niveau (it floats between two slabs), escalier_hauteur_incoherente (it stops short of the floor above), escalier_chevauche (two flights in the same footprint), and escalier_sans_appui (free-standing mid-room — a WARNING, not blocking: an open stairwell is a legitimate choice). Each one comes with a `correctifs[]` entry carrying a REAL replacement position (x/y/rotation): the closest valid spot to what you asked for, backed against a wall, arriving in clear space and blocking no door. Apply with REST /api/v1/cao/integrite {appliquer:true, revalider:true} — you never have to guess where to put it. ALSO checks that a dormer sits on the slope (lucarne_profondeur_courte / _longue / lucarne_trop_haute — depth must be ≈ height / roof pitch, otherwise its roof floats above the slope or overshoots the ridge). Returns {ok, erreurs_schema, alertes[{code,severite,message,corriger}], conseils, resume}. Fix severite=critique before delivery. ALSO runs a full STRUCTURAL INTEGRITY check (is the building really closed and roofed?): enveloppe_percee — a wall end joins nothing (T-junctions and door jambs are recognised, so no false alarms) — murs_composantes_isolees — closed wall clusters / pillars / low walls scattered OUTSIDE the main envelope (the 'murs en vrac' Visite 4K defect; correctifs propose null = delete that wall) — bande_ouverte_entre_niveaux, mur_etage_sans_appui, toit_ouvert, toiture_sous_les_murs, ouvertures_chevauchantes, and the VOLUME CLASHES the IFC clash detector sees: mur_en_double, murs_superposes, mur_dans_une_baie (correctif slides the opening clear), volume_traverse_un_mur, volume_traverse_le_plafond, murs_qui_se_croisent (warning); pipe × wall crossings come back in `reservations` (sleeves to plan, not clashes). ALSO dalle_flottante / pilier_detache on orphan boxes. It returns `integrite.correctifs[]`: the exact field to write and the value to write there, e.g. {cible:'murs[3].x2', actuel:10400, propose:11000, raison:…} or {cible:'murs[12]', propose:null} to remove clutter. REST /api/v1/cao/integrite runs that check alone and can APPLY the fixes for you (appliquer:true, revalider:true) — also free, no key. Response includes `regles_archi` (buildingSMART-inspired principles). ALSO checks DOCUMENT COMPLETENESS (`documents`): the PDF planche delivers one full plan PER STOREY — 4 storeys means 4 complete plans — so it flags element_hors_plan (a stair/guardrail whose z attaches to no storey: it would vanish from EVERY plan), niveau_non_desservi (no stair ARRIVES at that storey and no lift covers it), arrivee_sans_protection (stair head without guardrail, NF P01-012), hauteur_niveau_insuffisante (<2200 mm). `documents.couverture` is the announced table of contents of the planche. Standalone: REST /api/v1/cao/documents (free, supports appliquer/revalider too). REST equivalent: /api/v1/cao/verifier.

WHEN the automatic visit is good but ONE view is wrong — the façade is cut off, the ridge is out of frame, you want to step into the next room — and rewriting a whole `chemin` by hand would be absurd. PILOT the camera with a SEQUENCE OF ACTIONS instead of coordinates: ['avancer x3', 'pivoter_gauche', 'monter', 'zoom_arriere']. Actions are named (avancer, reculer, gauche, droite, the four diagonals, monter, descendre, pivoter_gauche/droite, incliner_haut/bas, zoom_avant, zoom_arriere, vue_initiale, vue_ensemble, piece_suivante, piece_precedente) or given as the KEYBOARD SHORTCUT a human would press in the render studio ('ctrl+8' = forward, numeric keypad laid out as a compass rose). Same grammar both ways, so a view prepared here is reproduced exactly by hand. Start from `depuis` (any waypoint of a `chemin` from cao_visite_plan) or omit it for an overall view. POST THE SCENE TOO: it enables wall collision (a step that would end inside a partition is refused and explained, not silently applied) and the room landmarks. Returns {camera, etapes[] (state after EACH action, with the reason for refused steps), chemin[]} — feed `chemin` straight back to cao_visite_studio to render that exact viewpoint in 4K. Catalogue of actions and keys (free, no key): GET /api/v1/cao/visite/commandes. Requires API key. REST: /api/v1/cao/visite/camera.

WHEN the building should be SEEN in motion rather than read on a flat plan — you direct the shot. IMPORTANT: call cao_verifier FIRST and fix every severite=critique (intégrité clos/couvert + escalier/lucarne). This endpoint REFUSES with HTTP 400 construction_critique if the scene still has critical construction defects — the 4K visit would show them. Apply fixes via REST /api/v1/cao/integrite {appliquer:true, revalider:true} then retry. DIRECT the 4K cinematic visit of a CAO scene: choose the LENS (focal length in mm, full-frame equivalent) and the CAMERA PATH. Returns a shooting plan {plan:{objectif, cadence, plans[], chemin[]}, alertes[], resume} where `chemin` is the full waypoint list (position/vise in mm, CAO axes x=right y=depth z=height). Rooms are detected automatically (walls → flood fill → room centres → path through doorways), one interior walk per storey plus the stair climb. Rendering is done by ONE engine, the browser GPU: paste `plan` into CAO editor → « Visite 4K » → « Plan de caméra piloté », or call window.CAD_startCinematicTour({plan}). To adjust: resend with a modified `objectif`/`cadence`, or send back an edited `chemin` (it is then used verbatim and checked). Lens catalogue (free, no key): GET /api/v1/cao/visite/objectifs. Requires API key. REST: /api/v1/cao/visite/plan.
