If you typically begin a design by defining the duct runs according to system, select a duct tool
with a specific, predefined system, such as the Supply - Low Pressure tool. The duct that you
draw inherits the system’s properties, such as its design parameters, display properties, and rise
and drop style. For more information, see
on page 93.
NOTE
You can also begin drawing a duct run by clicking an
on a part, duct fitting, or duct
segment. Clicking the grip opens the Add Ducts dialog.
3
In the Add Ducts dialog, specify a system for System.
4
Specify a coordinate system and value for Elevation:
then…
If you want to…
select an elevation name for Elevation.
draw a run at a defined elevation
enter the desired elevation, specify justification and off-
set, and use AutoCAD snaps or AutoCAD MEP snaps to
specify points on the wall, duct, or other objects.
draw a run at a specified elevation relative to a wall
or other duct or duct
enter the desired elevation and use AutoCAD MEP snaps
to specify a point on the riser.
start a branch at a specified elevation on a riser
enter the desired elevation and use AutoCAD MEP snaps
to specify a point on the vertical run.
start a branch from a vertical run with a riser at a
specified elevation
enter the desired elevation, click Use Rise/Run, and use
AutoCAD MEP snaps to specify the endpoint of a sloped
duct or duct.
extend a sloped duct or duct segment to a specified
elevation
If you lock the elevation, the elevation from the objects that you connect to is not inherited.
5
You can specify the offset in 2 directions:
then select…
If you want to specify…
Left, Right, or Center. Enter the horizontal distance of
the run from the wall or other objects.
the horizontal offset
Top, Center, or Bottom. Enter the vertical distance of
the run from the ceiling or other objects.
the vertical offset
6
Specify connection type, duct shape, and duct size. To calculate duct size using the instant sizing
tool:
then…
If you want to…
accept the detected value for Capacity, or enter a value for
Capacity. Click
.
