Use when adding or editing OAS extension blocks — machinery, materials, site, MEP, or Autodesk metadata — that augment a Core or Layout document.
Use when writing or debugging OAS geometry — points, polygons, line segments, arcs, circles, spirals, fillets, units, or coordinate conventions. Load before any geometry-heavy edit.
Use when producing or editing fully resolved OAS-Layout JSON — multi-level plans with levels, rooms, walls, openings, slabs, roofs, furniture, railings, and inter-level connections.
Use when capturing OAS design intent — room requirements, area targets, adjacency rules, circulation rules, or global constraints — before any geometry has been resolved.
Use when mapping OAS plans to a visual output — SVG, Canvas, or WebGL — including scale, axis orientation, and z-order layering.

Reach for this skill any time you are emitting or modifying the foundational entities of an OAS plan: rooms, walls, openings, curtain walls, roofs, floor slabs, furniture, railings, or annotations. If the task is purely about coordinates and polygons, use oas-geometry instead. If the task is multi-level resolved geometry with stair/elevator connections, use oas-layout.
units block (always { length: "mm", angle: "deg" })Level — abstract reference plane at an elevation; not a physical elementRoom — bounded space with a boundary_polygon and usageWall — straight line segment with thickness separating spaces; carries adjacent_roomsOpening — door or window placed on a wall via position_along_wall_mmCurtainWall — glazed envelope; sibling of Wall, not a subtypeRoof — sloped covering with defines_slope and eave_overhang_mmFloorSlab — the physical floor element (distinct from an abstract Level)Furniture — placed objects with position + rotation (formerly an extension, now in Core)Railing — barrier element; path may include optional z on stair runsAnnotation — labels, dimensions, notes_mm field is an integer; angles use degrees. The only place decimals appear is derived area_m2.type_name on every entity. This is the IFC-style stable classification (e.g. IfcWall, IfcDoor). Vendor-specific families (Revit, etc.) belong in the oas-autodesk extension, never inline here.adjacent_rooms array — not on the room.IfcCurtainWall vs IfcWall). Don't nest one inside the other.position_along_wall_mm is measured along that wall's path; validate position + width ≤ wall length before emitting.See docs/core.md for the complete field-by-field reference.
