Returns or sets the scaling reference element.
It can be a point.
To set the property, you can use one of the following
Boundary objects:
PlanarFace or
Vertex.
Example:
The following example returns in ref the scaling
reference element of the scaling firstScaling,
and then sets it to the created MyRef:
Set ref = firstScaling.ScalingSupport
Set MyRef = part.CreateReferenceFromGeometry (Point)
firstScaling.ScalingSupport = MyRef
