Get and Set Hole Callout Variables Example (VBA)

This example shows how to get and set hole callout variables.

' Preconditions:
' 1. Open a drawing document containing a hole callout.
' 2. Select the hole callout.
' 3. Open the Immediate window.
' Postconditions:
' 1. Iterates through the variables in the hole callout and
'    gets any angle, length, and string callout
'    variables.
' 2. If the hole callout variable is a length variable,
'    then sets its precision and tolerance type.
' 3. Examine the Immediate window.
