MeshBooleanOperationsUsePolygonIndices Field

UsePolygonIndices is a static field that specifies if PolygonIndices from MeshGeometry3D are used to get initial polygons. When false (by default), then initial polygons are created from MeshGeometry3D.TriangleIndices (one polygon from one triangle). In some cases (box mesh) this can create a few more polygons, but in many cases (cylinder, sphere, etc.) this will create correct polygons because on meshes with curved surfaces polygons are not created from curved surfaces. See PolygonIndicesProperty for more info.
