After selecting a category of HVAC, choose a specific type of HVAC element from the
Available Types list.
When a selection is made from the Available Types drop-down list a separate window is displayed, input specific criteria based on what type of HVAC component is being created. For example: a prompt is displayed ‘to enter dimensions for a straight piece of ‘.
If the correct database hierarchy has not been configured beforehand certain Available Types are not available for selection. For example: certain HVAC elements must reside below other elements in the database hierarchy (an overview of the database hierarchy is described in
Hierarchy).
