Fields

product_id: u32

representation_id: u32

source_geometry_item_id: u32

geometry_item_id: u32

source_indices: Vec<u32>

source_positions: Vec<f32>

Canonical evaluated IFC Z-up geometry, before any appearance replacement. Coordinates are local f32 values plus source_origin and rtc_offset in metres.

source_normals: Vec<f32>

source_origin: [f64; 3]

source_color: [f32; 4]

rtc_offset: [f64; 3]

surface_fingerprint: String

Hex SHA-256 of the product GlobalId, its quantised local evaluated surface and topology. Face masks bind to this value; express ids are excluded so a renumbered export keeps its selection. The surface uses a precision-preserving product-local evaluation on every target, so a pure placement edit keeps the value while geometry or topology edits change it.

masked_triangles: Option<Vec<u32>>

Accepted ascending source triangle ordinals that received the appearance. Absent when the whole surface was converted.

retained_geometry_item_id: Option<u32>

The unmasked IfcTriangulatedFaceSet under the same Body wrapper. It keeps the source surface style and the complementary source triangles.

source_removed_meshes: Vec<MeshData>

Canonical opening meshes removed when their Body becomes Reference. Inner fields use the shared MeshData wire contract; origin + rtc_offset restores IFC Z-up metres. These owners are companion dependency roots.
