Struct StepProduct 

pub struct StepProduct {
    pub pd_ref: usize,
    pub name: String,
    pub id: String,
    pub bodies: Vec<BrepSolid>,
    pub appearances: Vec<BodyAppearance>,
    pub failed_bodies: usize,
    pub pmi: Option<PmiState>,
}

One node of the file’s product structure: a PRODUCT_DEFINITION, or a representation that a MAPPED_ITEM instantiates and no product definition owns (bodies::representation_owner_index).

Fields

pd_ref: usize

The node’s entity id — a PRODUCT_DEFINITION, or the representation that stands in for one. The stable identity and dedup key either way, because Part 21 ids are unique within a file.

name: String

PRODUCT.name, the representation’s name for a node that is one, or pd#<id> when the file carries neither.

id: String

PRODUCT.id — the vendor part number, for the BOM. May be empty.

The CONSUMER is what makes this durable: the app’s assembly intake records it as partAttributes.Part_Number on the part document it mints (BREP_render’s model_io.rs::part_attributes), which is the record io/step/export_tree.rs reads back out as PRODUCT.id. An intake that dropped it would silently replace a vendor’s part numbers with our own file names on the first export -> import -> export.

bodies: Vec<BrepSolid>

This product’s OWN solids, in its OWN local frame and at its OWN unit scale. Empty ⇒ a pure assembly node (structure, no geometry).

appearances: Vec<BodyAppearance>

The styled colour of each entry of bodies, PARALLEL to it (index i is body i). Default-filled when the file carries no presentation entities, so it is always the same length as bodies and a caller can zip without a length check.

failed_bodies: usize

Bodies of this product that did not reconstruct. Graceful degradation: counted, never fatal, and never a reason to reject the file.

pmi: Option<PmiState>

The file’s PMI that annotates THIS product’s own geometry, with references naming the faces / edges / vertices the part document’s IMPORT3D1 feature will stamp (assembly_pmi.rs).

ONE lift per PART, however many occurrences place it — an annotation on a part’s face IS an annotation on every instance of that part, which is the exporter’s rule read backwards (io/step/assembly.rs: two instances of one part share the part’s ADVANCED_FACEs). PMI the file pinned to a particular INSTANCE is not here; it rides StepAssembly::pmi.
