This example shows how to add a reference dimension to a model in a drawing.

' Preconditions:
' 1. Verify that the specified drawing document to open exists.
' 2. Open the Immediate window.
' Postconditions:
' 1. Opens the specified drawing document.
' 2. Activates a drawing view, selects an edge on the model, and
'    creates a dimension.

'    is a reference dimension.
' 4. Examine the Immediate window.

' save any changes.
