## Geometry2D.Normal

### Description

Get the normal at a given 2D geometry

### Scripting Syntax

    oBoolean = Geometry2D.Normal( compIdx, compNor );

### Return Value

Boolean. True if the normal is valid; otherwise False

### Parameters

Parameter | Type | Description
--- | --- | ---
compIdx | Integer | Index of the component
Possible Values: | Description:
0 | The compIdx must be valid
compNor | SIVector3 | Upon return, contains the normal at the (compIdx)th 2D component

### Examples

#### VBScript Example

    'Create a cube

    CreatePrim "Cube", "MeshSurface"

    set oSelList = GetValue("SelectionList")

    set oItem = oSelList(0)

    set oGeometry = oItem.obj

    oNb2D = oGeometry.Nb2D

    set o2DComponent = oGeometry.Geometry2D

    set oNor = XSIMath.CreateVector3()

    ' Loop on all the 2D Component

    for i = 0 to oNb2D - 1

    if o2DComponent.Normal( i, oNor ) then

    LogMessage "Component [" & i & "] normal : " & oNor.x & " | " & oNor.y & " | " & oNor.z

    end if

    next
