This tool lets you select components in a view to be added to a system.
When more than one system is associated with the selected component, the available systems are listed in the System Selector dropdown.
All except the components in the selected system are dimmed in the view, and the Edit Duct System or Edit Pipe System ribbon commands display. The Properties palette displays the System Name, System Equipment and the Number of Elements in the system.
The Add to System tool will only let you select components that are compatible with the selected system. For example, you cannot add an exhaust diffuser to a supply system, or a toilet to a closed-loop heating system.
The selected components are added to the system.
