    alignments? profiles? surfaces surveyPoints triangles vertices
    alignments?: number

    Horizontal alignments written as IfcAlignment (§11). landXmlToIfc always sets it; it is optional only so that adding it is not a breaking change to an interface v1.0 may already have published (#5370 review) — read it as coverage.alignments ?? 0.

    profiles?: number

    Design profiles written as IfcAlignmentVertical (§12). Optional for the same reason as alignments: read it as coverage.profiles ?? 0.

    surfaces: number

    TIN surfaces written as IfcGeographicElement/.TERRAIN..

    surveyPoints: number

    <CgPoint> records written as IfcAnnotation/.SURVEY..

    triangles: number

    Triangles across all written surfaces.

    vertices: number

    Vertices across all written surfaces.
