Struct StepExportOccurrence 

pub struct StepExportOccurrence {
    pub designator: String,
    pub parent: usize,
    pub child: usize,
    pub placement: Mat4,
}

One placement of child inside parent — a NEXT_ASSEMBLY_USAGE_OCCURRENCE.

Fields

designator: String

The instance label: the placing component’s id (ACOMP3). Written into the NAUO’s reference_designator, which is what the importer reads back first, so an instance keeps its identity through the round trip.

parent: usize

Index into StepAssemblyExport::products.

child: usize

Index into StepAssemblyExport::products.

placement: Mat4

child-local -> parent-local, row-major affine. Must be RIGID: a mirrored or scaled instance has no AXIS2_PLACEMENT_3D and is rejected rather than silently written as its rotation part.
