Use the Analytical Connections tool to create an analytical connection between a pipe connector on mechanical equipment and the curve connector along a pipe or end connector on a pipe, without physically connecting.

To add an analytical pipe connection from the equipment
When you create or maintain hydronic piping models, you can save time by creating analytical connections between connectors on mechanical equipment and pipework.
You can add analytical connections by selecting the equipment first or the pipework first. The following procedure lists the steps when you select the equipment first.
The cursor displays with a plus sign.
The analytical connection uses a point on the perpendicular projection from the connector on the family. if a perpendicular point doesn't exist, the connection is added to the closest end of the pipe.
If the selected pipe has an open end connector, the analytical connection will attach to the open pipe connector.
You can turn off the display of analytical connectors, and the flow and pressure properties from the equipment will continue to be used with the network calculations. On the View Control Bar, click (Hide Analytical Model).
You can assign a pressure drop in the Type Properties dialog for Analytical Pipe Connections. The property defaults to zero.
