You can begin a Routing operation by placing a junction at an already placed straight MEP segment.
•Click Start Routing on the MEP Routing palette
•Click on the centerline of a placed MEP element
The Routing will begin at the place you clicked, by inserting a Junction.
The Insert Junction Element dialog box appears. Choose the type of junction you wish to insert (e.g. Duct Tee, Duct Takeoff, Duct Wye), then click OK. (The possible junction types vary depending on whether the clicked element is a Duct, a Cable or a Pipe.)
Next, depending on the Junction type you choose, you may be prompted to choose among several possible geometries:
If you place a Duct Wye junction, you must click twice:
•First, click to define which side of the existing element to place the Wye.
•Second, click in either direction to define which of the two Wye branches to connect the next routed element.
If you place the Duct Take-off in Floor Plan:
1.First, click to define which side of the element (right, left, top, bottom) to attach the takeoff.
2.If you click “top”, then the program assumes that the next placed element will be at a right angle to the takeoff, and you are prompted to choose one of the four horizontal directions shown as you move the cursor around the insertion point on screen.
(If you prefer that the next placed element be vertical, do not choose any of the four horizontal directions indicated by the on-screen feedback. Instead, switch the Construction Method (use the MEP Routing palette or the Tracker) to Vertical Rise and place the next element.)
3.After you place the horizontal segment, Guide Lines will prompt you to click to define the angle at which to continue the next routing element.
Similarly, if you place the Duct Tee in Floor Plan, Guide Lines will prompt you to click to define the angle at which to continue the next routing element.
The newly placed MEP elements will use the parameters (Element type, MEP system, shape, elevation) of the clicked connection port, overwriting the current parameters of the Routing palette with those of the clicked connection port.
Note: Several MEP elements placed at varying elevations can appear, on the Floor Plan, to have connection points that coincide. If you begin routing by clicking on one of these connection points, you will be prompted to choose the connection port you want.
