Video: Use Multi-Point Routing with MEP Fabrication Parts

Create a run of connected MEP fabrication parts by clicking points in the model.

This video demonstrates the following:

1. Start the Multi-Point Routing tool.
2. Select points in the drawing area to create a run of fabrication piping.
3. Make changes to the layout.

In Revit, use the Multi-Point Routing tool to quickly draw a run of MEP fabrication parts by clicking in the drawing area. Parts from the currently selected Service and Group are automatically inserted. To begin, make sure the MEP Fabrication Parts browser is displaying, and that the desired Service and Group are selected.

You can start the Multi-Point Routing tool using any of the following methods:

• In the ribbon, click the Systems tab, then click the Multi-Point Routing button on the Fabrication panel.
• In the Parts browser, click the Multi-Point Routing button.
• In a model, right-click an open connector on a fabrication part, and select Multi-Point Routing from the right-click menu.

In this example, we'll start by inserting a 6-inch hot water service main at an 8-foot offset. In the Properties palette, specify the size as 6inches, and set the offset to 8 inches.

In the drawing area, click to specify the start point for the first part in the run, then click again to specify the end point. Continue clicking points in the drawing area to add more parts to the run. You can change the offset or size as needed.

For example, to change the offset for the next part, specify the new offset in the Properties palette. Here, two 45-degree bends were automatically inserted to accommodate the offset. A deeper offset may have automatically inserted 90-degree bends instead.

In this example, we'll change the 6-inch pipe to a 5-inch pipe. To change the size of the part being inserted, specify the new size in the Properties palette, and then click the next point. The smaller pipe is inserted, along with the appropriate reducer to accommodate the transition.

To insert a branch off a main run, press Escape twice to end the Multi-Point Routing command. Make sure the desired Service and Group are selected. Click the Multi-Point Routing button again to start the command. Now click on the centerline of the main to insert the branch. Notice that the current offset and other values are inherited from the main. Here we'll insert a 1-inch pipe, and change the offset to 8 feet, 6 inches.

To insert ductwork, the process is the same. Start by selecting the desired Service and Group in the Part Browser, then start the Multi-Point Routing command.

In the drawing area, specify the start point to insert the first part. In the Properties palette, specify size and offset as needed. While the Multi-Point Routing command is active, use the Type Selector to change shape if needed.

Here we'll change from Rectangular to Round, and set the size and offset too. While the Multi-Point Routing command is active, use the Auto Fill Tool Exclusions feature to force a specific part to be inserted. For example, to use a 30-degree bend, exclude all other bends in the Parts browser. Continue clicking points in the drawing area to complete the run. When finished, press Escape twice to end the command.

The Multi-Point Routing tool significantly reduces the time it takes to design MEP fabrication models in Revit.
