The Connect components tool is used to create connections between the inlets and outlets of both air-side and water-side components. The tool can only be used at the sub-loop level. HVAC connections are created in the form of a number of segments or steps, each segment snapped to the X or Y axis. To create a connection between two components, first click on the Connect components tool and move the cursor to the required component inlet/outlet. When the cursor is over the required inlet/outlet, a green connection marker will be displayed to indicate that the beginning of the connection can be snapped to the inlet/outlet:
You can then click the mouse button to start the connection. Having snapped the beginning of the first connection segment to the required inlet/outlet, as you move the mouse cursor away, the cursor will automatically snap to the X or Y axis depending on the position of the cursor relative to the connection point. As you move the cursor across the screen, drawing guides are displayed to indicate that the current cursor position has been automatically snapped to align with existing connections in the X and Y axes:
When the cursor snaps to a required drawing guide, you can then click the mouse button to place the end point of the current connection segment. Finally, as you move the cursor towards the component inlet/outlet to which the connection is to be created, a green connection marker will again be displayed to indicate that the end of the connection can be snapped into position by clicking the mouse cursor button.
