This example shows how to open a part document from an assembly document.

'---------------------------------------------------
' Preconditions:
' 1. Open an assembly.
' 2. Select a vertex, face, or an edge of a component.
' 3. Open the Immediate window.
'
' Postconditions:
' 1. Opens the part document to which the selected vertex, 
'    face, or edge belongs.
' 2. Examine the Immediate window and graphics area.
