You use the Pipe Fitting tool to add flanges to a piping system. Before displaying flanges, you must specify the default flange type in the Type Properties dialog.
In the Project Browser, open the view where you want to place the flange.
In the Project Browser, expand FamiliesPipesPipe Types.
Right-click pipe type, and click Properties.
In the Type Properties dialog, under Type Parameters, under Mechanical, specify the default flange fitting type used with the selected pipe type.
Note: The default Flange type is None. If set to None, no flanges display for that pipe type.
Click OK.
Click Systems tabPlumbing & Piping panel Pipe Fitting.
Note: The flange that is selected in the Type Selector is drawn in the model regardless of what type of fitting the pipe connects to. The size of the drawn flange depends on the size of the pipe. Ensure that you select the correct fittings and flange type in the Type Properties so that they fit correctly.
Select a pipe end/fitting to connect the flange to.
