Design criteria for placeholder ducts
Within Revit ducts are system families, and they are the glue that hold
systems together. However, it also relies on component or loadable families
to create a duct type, as described in the next section. Although ducts hold
a huge amount of information, for the user there are several important
considerations to note, such as the type of bends, transitions, and other
fittings that make up the duct run. Also take into consideration lining and
insulation, which can be applied to runs or parts of runs after placement.
Since Revit MEP 2014, we have had the ability to specify the type of system
that a duct is associated with (exhaust, return, or supply), without actually
being connected to any equipment. You will be able to change the system
type of a duct, even after it is connected to equipment, but not the
classification. For example, if your duct is connected to a supply terminal,
then you can change your system type to Outside Air, but not to return or
exhaust air, as the Oustide Air System type should have been created from
the Supply Air System Classification. If your duct is not connected to any
equipment, you can change it to any system you like, as shown in
