Struct StepOccurrence 

pub struct StepOccurrence {
    pub nauo_ref: usize,
    pub parent: usize,
    pub child: usize,
    pub designator: String,
    pub placement: [f64; 16],
    pub rigid: bool,
}

One NAUO occurrence: a placement of child inside parent.

Fields

nauo_ref: usize

NEXT_ASSEMBLY_USAGE_OCCURRENCE entity id.

parent: usize

Index into StepAssembly::products.

child: usize

Index into StepAssembly::products.

designator: String

The instance label (“bolt-3”) — see [nauo_designator] for which of the NAUO’s several label attributes wins.

placement: [f64; 16]

child-local → parent-local, row-major affine, translations in MILLIMETRES (scaled by the PARENT representation’s unit, which is the frame the placement is expressed in). NOT a world transform: the caller composes these down from StepAssembly::roots.

rigid: bool

RᵀR = I and det R = +1 within 1e-9 — i.e. the placement is a pure rotation + translation, representable as a translate/rotate component pose. A mirrored or scaled occurrence has no such representation and its non-rigid factor must be baked into a distinct part by the caller.
