Callouts are replicas of Mark objects that do not influence the Bar Bending Schedule and the quantity take-off. They are primarily used to insert annotations whose content reflects the Mark data. The number of bars displayed by a Callout are a mere reflection of the linked Mark and they do not contribute to the total quantity take-off.
