Get Linked Dimensions Example (VBA)

This example shows how to get the linked dimensions in a part document.

'---------------------------------------------
' Preconditions:
' 1. Open public_documents\samples\tutorial\lesson2\tutor1.sldprt.
' 2. Right-click Annotations and click Show Feature Dimensions.
' 3. Right-click either 120 dimension and click Link Values.
' 4. Type AreaDimension and click OK.
' 5. Right-click the other 120 dimension and click Link Values.
' 6. Type AreaDimension and click OK.
' 7. Open the Immediate window.
'
' Postconditions:
' 1. Examine the Immediate window.
' 2. Click either 120 dimension, change 120 to 150, and press Enter.
' 3. Changes the other 120 dimension to 150 because the dimensions
'    are linked.
'
' NOTE: Because the part is used elsewhere, do not save changes.
