You use the Connect Into - Duct/Pipe tool to automatically add a component and create piping between the new component and the existing system.
If the new component could be connected to more than one system, the Select Connector dialog opens. Each piping connector is listed with its index number, System Classification, shape, size, Connector Description, and flow direction. The Connector Description may be used to indicate the System Type that should be assigned to the connector. An arrow shows the location and direction of the selected connector.
The cursor displays with a plus sign.
The new component is added to the system.
