PolygonFaceCollection.PolygonNodePolygonFaceIndexArray operator

Description

Returns a 1-dimensional Array containing the number of PolygonNodes on each PolygonFace followed by each index PolygonNode ordered within the PolygonFaceCollection. For example, if you have a mesh containing 3 PolygonNodes you might get this array: '4, 0, 1, 2, 3, 3, 4, 5, 6, 4, 7, 8, 9, 10'.

C# Syntax

// get accessor

Object rtn = PolygonFaceCollection.PolygonNodePolygonFaceIndexArray;

VBScript Example

' Get the facets on the mesh

set oPolygonFaceCollection = oPolygonMesh.Polygons

' Get the node number/index array and loop through the array, printing the info
