Get the normal at a given 2D geometry

oBoolean = Geometry2D.Normal( compIdx, compNor );

Boolean. True if the normal is valid; otherwise False

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

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
