Couplings

To jump to a video explaining the Couplings button, click here.

The Couplings button is used to insert multiple couplings along a run of pipe, as opposed to a single coupling using Revit's Split Element command. There are a few ways to add couplings using this tool, inserting couplings along only a single run of pipe, using continuous selection in order to select many runs of pipe, or placing couplings at the specific points a detail line passes over piping.

Summary

• Select the Couplings button from the HydraCAD ribbon.
• From inside the dialog box, you have multiple inputs that can specify the distance between couplings, Maximum Distance to Existing Fittings (This can also be interpreted as Minimum Distance to Existing Fittings) will tell the coupling not to be cut in if its too close to a POL, etc. Coupling Gap is a field where you can enter the gap of the coupling to avoid any issue with the fabricator regarding the pipe being longer than anticipated.
• Continuous Pipe Selection should be checked if you want to apply couplings to multiple runs of pipe, like all the branchlines for example. Leave unchecked for a single run.
• Break Couplings Over Line is used if you'd like to draw a detail line, splitting either one or multiple pipe at a desired position. You can click that line and it will put couplings where it intersects with any pipe beneath it.
• Checking any of the options to add dimensions will add them as couplings are cut in, according to whichever ones were selected. (Dimensions between couplings, Dimension pipe segments, etc.)

How Do I Use The Button?

The Pipe Type / Routing Preferences / Union determines the family being used for the couplings.

Imperial

Distance between couplings, input as decimal feet. Maximum distance from a fitting, input as decimal inches. Metric

Distance between couplings, input as decimal meters. Maximum distance from a fitting, input as decimal millimeters.

Add Couplings

Continuous Pipe Selection:

If checked, you will be prompted to select another Detail Line. Right click mouse to Cancel, or Esc to quit.

Note: Coupling pipe run stops at an existing coupling, a change in direction (elbow), or a tee or cross with the same diameter outlets as the run’s pipe diameter.

Dimension Between Couplings

Note about couplings along sloped pipes and dimensions… Plan view dimensions may be shorter or longer, depending on the pipe slope.

Dimension Pipe Segments

Fix and Associate Hangers

If checked, Ensure hangers and braces are attached to the newly created pipes.

This option may cause the tool to run much slower, regardless of the presence of hangers.

Break Couplings Over Line

Detail lines need to be added to view prior to running the command.

You will be prompted to select a detail Line.

Continuous Pipe Selection

If checked, you will be prompted to select another Detail Line. Right click mouse to Cancel, or Esc to quit. Couplings will be added at intersection of Pipe with Detail Line.

Remove Couplings

Will remove the couplings along the run of selected pipe.

Cancel

Cancels command and closes dialog box.
