    polylines: ProductPolyline[];
    positions: Float32Array;

Properties

globalId: string | undefined

id: bigint

In authored order; empty with no refusal: no such curves.

positions: Float32Array

x, y, z per vertex, metres, relative to transform: every polyline in turn.

refusal: GeometryRefusal | undefined

skipped: bigint[]

The representation's text literals and annotation fill areas, by entity id in authored order: not drawn, and not a refusal (#512).

transform: Matrix4 | undefined

World placement; a vertex's world position is transform * position.

typeName: string

vertexCount: number
