Get Normal of Planar Surface Example (VBA)

This example shows how to the normal parameters of a planar surface.

'----------------------------------------------
' Preconditions:
' 1. Open a part, assembly, or drawing.
' 2. Select a face on a planar surface.
' 3. Open the Immediate window.
'
' Postconditions: Examine the Immediate window.
'
' NOTE: The normal of a surface (ISurface::PlaneParams)
' cannot be in the same direction as the normal
' of the face (IFace2::Normal).
