Flange
These can be placed at the end of pipes or face to face with
another flange.
Using Pipe Fitting Controls
Understanding pipe fitting controls can really make life easier if you are
routingalotofpiping. Whenyouarelayingoutyourpiping, turn90degrees
to create an elbow. If you click the elbow, you will notice a plus (+) sign.
If you click that sign, it will change from an elbow to a tee, allowing you to
add more piping and continue your pipe routing. If you click the minus (-)
sign, it will downgrade the fitting. When you see the symbol on a fitting,
it allows you to rotate the fitting, and the
symbol allows you to flip the
fitting.
The display of both fittings and valves can be challenging as you rotate the
elements to represent the actual needed position. In some cases, they may
become invisible. For example, when you place a valve in plan view at either
coarse or medium detail level, you will see its symbolic representation, but
if you go to a section, you won't see the valve at all. However, if you change
it to fine detail level, you can see the geometry of the valve. This is because
the valve is displayed as a symbol when showing single-line pipes, and with
all of its 3D modeled geometry when in double-line pipe views. Currently
the symbol can be displayed in only two opposite views (two sections, or
floor plan and ceiling—in all other views it will be invisible). This is a known
limitation with Revit, and to avoid it you should consider developing a
standard for displaying valves and fittings, and at a certain level of detail.
Placing Valves
When you need to add valves to your piping, select the System tab and then
select Pipe Accessory. Use the Type Selector to select the type of valve you
want to use. Most valves are
break into
types, so you can place them into
a pipe run and they will break into the piping, maintaining connections at
either end (see
Figure 11.20
)
. This behavior works even when you remove
the valve: The pipes automatically fill in the gap where the valve used to be.
