You can draw duct runs in all 3 dimensions. You can also add sloped runs by specifying rise/run values. As
you draw duct runs, fittings are automatically inserted to accommodate your routing geometry. The layout
preferences specify which fittings are used. For more information, see
Specifying Default Parts for Layout
on page 180.
1-line and 2-line duct runs can be routed 3 dimensions.
You can size duct systems using engineering analysis tools included in AutoCAD MEP. You can use a
to size duct systems, and you can use
in the Add dialog
and Modify dialog to size individual segments.
Flexible Duct Runs
You can draw flexible duct runs. Flexible runs can be connected to rigid runs to create complete and accurate
networks. Because flexible ducts are typically round in shape, the correct transition fitting is inserted when
you connect to a duct segment of a different shape. You can specify a system for flexible duct components
just as you can with rigid duct. You can also assign flexible and rigid components to the same system.
Flexible duct runs can be connected to equipment and MvParts.
You can draft a flexible duct run using different segment modes. Individual segments can be drafted as lines,
arcs, or splines to create different configurations of flexible runs. For more information, see
on page 179.
You configure the display properties of flexible duct using several display components:
■
Contour.
Use this component to configure the contour lines.
■
Contour - Details.
Use this component to configure the interior contour lines.
■
Connector.
Use this component to configure the connector lines at start points and endpoints.
■
Annotation.
Use this component to configure the graphics pattern.
