Change Material Properties Example (VBA)

This example shows how to change the color of the selected assembly component.

'----------------------------------------------------
' Preconditions:
' 1. Open public_documents\samples\tutorial\api\landing_gear.sldasm.
' 2. Click oleostrut<1> in the FeatureManager design tree.
' 3. Open the Immediate window.
'
' Postconditions:
' 1. Changes the color of the selected component to blue.
' 2. Examine the component in the graphics area and
'    the Immediate window.
'
' NOTE: Because this assembly is used elsewhere, do not save
' changes.
