The example drawing converted to a sized 2-line duct system.
If any errors occurred during calculations, click View Event Log to see a description of the error.
Note that duct segments are not broken into multiple segments. The calculated duct size is applied to the
entire duct segment. For example, you may want to reduce the duct size at all points where the system

Adding a Duct Fitting Manually
Typically, AutoCAD MEP adds fittings as you draw a duct run based on the default fittings specified in the
. However, you can also add them manually. You can add a fitting to an existing
segment or run. You can also add a fitting from which to start a segment or run, or to customize the
connection to a part.
You manually add duct fittings using the tools on the Fitting tool palette in the HVAC tool palette group.
You select a tool, use the Add Duct Fittings dialog to select the fitting and configure its properties, and then
add the fitting to the drawing.
