API Reference > geometry-core > Polyface > PolyfaceQuery > markPairedEdgesInvisible markPairedEdgesInvisible MethodStatic Find mated pairs among facet edges. Mated pairs have the same vertex indices appearing in opposite order. Mark all non-mated pairs invisible. At mated pairs if angle across the edge is larger than sharpEdgeAngle, mark visible otherwise mark invisible. markPairedEdgesInvisible(mesh: IndexedPolyface, sharpEdgeAngle?: Angle): void Parameter Type Description mesh IndexedPolyface mesh to be marked sharpEdgeAngle Angle Returns - void Defined in core/geometry/src/polyface/PolyfaceQuery.ts Line 841 Last Updated: 13 June, 2024
