Change Dimensions of Gear Mate Example (VBA)

This example shows how to change the dimensions of a gear mate.

'---------------------------------------------------------------------
' Preconditions:
' 1. Verify that the assembly to open exists.
' 2. Open the Immediate window.
'
' Postconditions:
' 1. Opens the assembly.
' 2. Selects a face on middle-gear<1> and a face on shaft gear<1>.
' 3. Adds a mate called GearMate1.
' 4. Gets and sets the dimensions of GearMate1.
' 5. Expand MateGroup1 and edit GearMate1.
' 6. Examine the Immediate window to verify that the values shown
'    there match the ratios shown in the GearMate1 PropertyManager page.
'
' NOTE: Because the assembly is used elsewhere, do not save changes.
