In this lesson you will modify the diameter of the pipes so that the pipes are a better fit with the design specifications. Click the Menu Browser and select Open and from the Training Files, Imperial, Fire Protection Systems Folder, open the file RME FP Design 05. Then open the View 3D Fire Protection and tile the views and arrange them so that they are tiled horizontally. Adjust the view in both windows to view the entire fire protection pipe run as shown. It's important to recognize the distinction between sizing and manually changing the diameter, height or width. Changing the diameter, width or height of pipe on the Options Bar is not considered sizing in Revit MEP. Sizing is performed using the Sizing Tool in the Sizing Dialog to size the pipe based on a series of parameters and calculations. The calculated size of a pipe is the result of the Sizing Tool and not the result of a manual change of diameter, width or height. Let's modify the diameter of the fire protection pipe run. In the Plan View, draw a selection box around the piping until just past the section line. Do not include the supply pipe or hose reel cabinet. Then click Filter. In the Filter Dialog click Check None and select Pipe Fittings and Pipes and click OK. Then on the Options Bar, for Diameter, select 1 Inch. Then press Escape. Next we'll tag the pipes. Zoom into the right half of the wing and if necessary, from the View Tab, Graphics Panel, click Thin Lines. Then click the Annotate Tab and from the Tag Panel click Tag by Category. Then select a segment of pipe in the corridor and in the Revit Dialog click Yes to load a tag. From the Training Files, Imperial, Fire Protection Systems Folder, double click Pipe Size Tag and on the Options Bar, Clear Leader and place the tags as shown. Press Escape and Next, we will modify the diameter of the main. In the 3D View, select the Linked Architectural File and on the View Control Bar, click Temporary Hide Isolate and click Hide Category. Select the vertical pipe below the hose cabinet as shown and then place the cursor over the section of main pipe feeding the last sprinkler and press Tab. When the pipe between the vertical pipe and the last segment highlights, click to select the main piping between these points. The on the Options Bar for Diameter, select 4 Inches and press Escape, clicking the Floor Plan View and close the 3D View and maximize the Floor Plan View. Next we'll modify the diameter of branch pipes. Select the top segment of branch pipe as shown and on the Options Bar, for Diameter, select 1 and a Quarter. The number of sprinklers serviced by a branch determines the pipe size used for that branch. Using the same method, change the diameter of the other top segments to 1 and a Quarter and when finished, clear the selection and close the file without saving it as the next lesson will provide its own training file and that concludes this lesson.
