## PolygonFaceCollection.PolygonNodePolygonFaceIndexArray

### 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;

### Examples

#### VBScript Example

    NewScene , false

    ' Create a cube and then slice one of the polygons (to get an irregular # of nodes)

    set oObject = Application.ActiveProject.ActiveScene.Root.AddGeometry("Cube","MeshSurface")

    ApplyTopoOp "SlicePolygons", oObject & ".poly[4]", siUnspecified, siPersistentOperation

    ' Get the facets on the mesh

    set oPolygonMesh = oObject.ActivePrimitive.Geometry

    set oPolygonFaceCollection = oPolygonMesh.Polygons

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

    aPolygonNodePolygonFaceIndexArray = oPolygonFaceCollection.PolygonNodePolygonFaceIndexArray

    i = 0

    for each oPolygonFace in oPolygonFaceCollection

    	Application.LogMessage "There are " & aPolygonNodePolygonFaceIndexArray(i) & " PolygonNodes on this PolygonFace "

    	nodecount = aPolygonNodePolygonFaceIndexArray(i)

    	i = i + 1

    	results = vbTab & "The indices for those PolygonNodes are :"

    	for j = 0 to nodecount-1

    		results = results & " " & aPolygonNodePolygonFaceIndexArray(i)

    		i = i + 1

    	next

    	Application.LogMessage results

    next
