the system. Therefore, it will still be necessary to understand how to create
and manage systems manually.
You can remove elements from a system using the Remove From System
button when editing the system. You can also do this by right-clicking the
connector symbol and selecting Remove From System. You can use either
method only if the element is not physically connected to any other piece
of the system (including ductwork). Once all elements have been removed
from the system, the system itself will be removed from the Revit file. You
can also delete the system from the System Browser. This will reset all
elements in the system to Unassigned and set the ductwork to Undefined.
Setting Up Piping Systems
Mechanical piping benefits greatly from systems in Revit MEP 2015.
Graphics, annotations, flow, and pressure loss can all be handled with a
small amount of setup in your project template. Pipe systems also allow
filters to apply to all components in the system, including the fittings. Also,
the System Browser acts as a graphical pointer to the designer with regard
tohowobjectsareconnected insystems; italsoprovides benefits intermsof
how the actual systems perform.
The first of these benefits is the ability to predefine the system in which
pipes (and ducts) are created, allowing layouts to be designed without the
need to set up systems in the first place. This allows the designer to create
hot-water (HW) and cold-water (CW) pipe runs with graphical filters
already in place to display the different systems being created.
Second, this allows for different systems to be interconnected. In order to
do this, you just need to specify which system you wish to use before placing
each piece of pipe.

2 selected. When you are working with multiple systems that are connected,
a fitting, an accessory, or equipment is needed between the two pipes or
ducts for the separation of the systems to work. When the system change
occurs at an elbow or tee, all is good. However, when you want to change
the system but continue the pipe/duct in the same direction as the original
one,youneedtousetheSplittooltoinsertacouplingfittingsoyoucanhave
two systems. Even though everything seems to work visually when you have
multiple systems connected in such a way, it is only for graphical purposes.
