## Geometry1D.AverageNormal

### Description

Get the average normal of given 1D geometry

### Scripting Syntax

    oBoolean = Geometry1D.AverageNormal( compIdxArray, compNor );

### Return Value

Boolean. True if the average normal is valid; otherwise False

### Parameters

Parameter | Type | Description
--- | --- | ---
compIdxArray | Array of Integer values | An array of indices of 1D geometry
Possible Values: | Description:
0 <= compIdxArray(i) < Number of 1D geometry | Each index in the array must be valid
compNor | SIVector3 | Upon return, contains the average normal of the given 1D geometry

### Examples

#### VBScript Example

    'Create a cube
    CreatePrim "Cube", "MeshSurface"
    set oSelList = GetValue("SelectionList")
    set oItem = oSelList(0)
    set oGeometry = oItem.obj
    oNb1D = oGeometry.Nb1D
    set o1DGeometry = oGeometry.Geometry1D
    set oNor = XSIMath.CreateVector3()
    ' Construct an array containing the indices 0,1,2,3
    dim oIndicesArray
    oIndicesArray = Array( 0, 1, 2, 3 )
    if o1DGeometry.AverageNormal( oIndicesArray, oNor ) then
    LogMessage "Average normal of Component (0, 1, 2, 3) : " & oNor.x & " | " & oNor.y & " | " & oNor.z
    end if
