To Draw a Flexible Pipe Run

1. In the Piping workspace, click Home tab Build panel Tools drop-down Tools .
2. Select a flexible pipe tool from the Piping tool palette.
   Tip: You can also use the PIPEFLEXADD command or hold down the Alt key for the same result.
3. On the Properties palette, under General, specify a system.
4. Under Dimensions, specify a routing preference.
5. Select a nominal size for each pipe connector.
6. Under Placement, specify an elevation.
7. Under Routing Options, for Segment, specify the layout method for the flex pipe as follows:

   If you want to…	then…
   lay out the flex pipe as a series of straight line segments	select Line for Segment. Specify a value for Radius factor. Any angled transitions in the flex pipe segment use this radius value.
   lay out the flex pipe as a series of arcs	select Arc for Segment.
   lay out the flex pipe as a complex curve by specifying points for a spline	select Spline for Segment.

8. Expand Advanced Graphics. Under 1-Line, select an annotation pattern for Graphics.

   This pattern is applied to flexible pipe runs after you draw them, and it is visible for flexible pipe systems displayed as 1-line.

9. Specify a value for Pitch.

   The pitch specifies the interval between the pattern, based on the drawing scale.

10. Repeat the previous steps for 2 Line and click OK when done.

    This pattern is visible for flexible pipe systems displayed as 2-line.

    Tip: You can use pipe curve or pipe end connectors to connect a flexible pipe run with a rigid pipe object. You can use flexible and rigid pipes in the same system while maintaining connectivity throughout the system.
Note: You cannot draw a sloped flexible pipe run in AutoCAD MEP 2022 toolset. As a result, properties related to Sloped Piping will not appear on the Properties palette.
