In-Depth Information
However, applying a material to a system applies that material to the
whole system, ducts, air terminals, and air handling equipment.
Calculations
You can set the calculations to All, Flow Only, or None.
The more calculations allowed, the more powerful Revit 2015 and
specifically the systems in it can be; however, this comes at a cost to
performance. Which setting is used here is dependent on the project
itself and the level of in-model calculations required. Remember that
this setting can be changed at any time and it is probably best that it be
set to None or at least Flow Only except for the specific times that all
calculations are needed.
System Classification
The System Classification value is the original,
or parent, system. This value, which is read-only, shows which type of
connectors the system can connect into and is decided by the original
system (Exhaust, Return, or Supply) that was duplicated to create the
system you are working with.
TypeImage
New to families in Revit MEP 2015, this provides the
ability to set an image file that can then be used in schedules. For duct
systems, this should probably be an image of the parent equipment for
the system, that is, the VAV or air handler.
Abbreviation
This bit of data can be very useful because it can be
tagged. Also, an abbreviation is neater on the drawing than using the
entire system name.
Type Comments
As with comments, type comments can be useful for
filtering or tagging that may be different for different systems in the
project.
URL
Used to provide an external link for more information on the
system.
Description
Used for descriptive information about the system.
Rise / Drop Symbol
Here you can specify which rise / drop symbol,
from a fixed list of available symbols, to use for each system. Generally,
supply air would be a cross and exhaust air would be a slash. Project or
company standards will determine whether the symbols should be filled
or if different symbols are to be used.
