Unlink Dimensions Example (VBA)

This example shows how to unlink dimensions in a part.

'---------------------------------------------
' 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. Removes the links from the linked dimensions.
' 2. Examine the Immediate window and graphics area.
'
' NOTE:
' * This macro gets all dimensions in the part, including dimensions
'   that are not associated with a feature. These types of
'   dimensions usually appear under Annotations.
' * Because the part is used elsewhere, do not save changes.
