OptionalapplyApply mutations (default: true if mutation view provided)
OptionalauthorAuthor name
OptionaldataData version identifier
OptionalhiddenHidden entity IDs (local expressIds)
OptionalincludeInclude geometry as USD meshes (default: true)
OptionalincludeInclude properties (default: true)
OptionalisolatedIsolated entity IDs (local expressIds, null = no isolation)
OptionalonlyOnly export properties with known IFC5 schemas (default: true). When false, all IFC4 properties are exported even if they lack an official IFC5 schema definition (viewer may show warnings).
OptionalonlyOnly export entities reachable from the spatial tree (default: true). When true, relationship entities (IfcRel*), type objects, materials, and other non-spatial entities are excluded from the output.
OptionalprettyPretty print JSON (default: true)
OptionalstripA namespace prefix to remove from GlobalId-derived node paths (#4444). A
store reconstructed from a shared room keys its entities by room path,
/<slotId>/<GlobalId>; the slot is the room's namespace, not the
model's, so the exported file carries /<GlobalId> — the same paths a
single-model room exports. GlobalIds outside the prefix are untouched.
OptionaltextureOriginal image bytes keyed by exact MeshTextureRef.url; retained in IFCX without recompression.
OptionalvisibleOnly export visible entities
