To Draw Flexible Duct

1. In the HVAC workspace, choose an action below:
   • Click Home tab Build panel Duct drop-down Flex Duct .
   • Open the Duct tool palette, and select the Flex Duct tool.
   • Press Ctrl and click the Add grip on a MvPart, or duct segment.
2. In the Properties palette add a description and specify a system.
3. Specify a routing preference, the diameter, and an elevation.
4. If you are using the line segment mode, specify the offset as follows:

   To specify…	then select…
   the horizontal offset	Select Left, Center or Right Justification. Enter the distance of the run from the wall or other horizontal object.
   the vertical offset	Select Top, center or Bottom Justification. Enter the distance of the run from the ceiling or other vertical object.

5. Under Routing, select (Line), (Arc), or (Spline).
   Note: Justification and Radius are not applicable for Arcs and Splines.
6. Specify a start point.

   If using the Spline segment mode, specify a start tangent point or press Enter for none.

7. Continue to specify points to add more segments to the run.

   To switch between segment modes during layout, enter l (line), a (arc), or sp (spline).

   Line and arc segments are joined together to create a single segment in the run. Spline segments remain separate segments in the run.

   To switch between planes during layout, enter p (plane) to toggle between the X, Y, and Z axes.

8. Press Enter to end the command.

   If drafting a spline segment, specify an end tangent point or press Enter for none. The flexible run is displayed.

   If drafting a line or arc segment, press Enter or click Close. The flexible run is displayed.

   Note: To draft multiple flexible runs, click New Run to end the current run and start drafting a new run without ending the command.
