The Pipe Break Group dialog allows you to add pipes to a pipe break group by either:

1. Picking a previously created selection set using the selection set button.
2. Picking pipes individually from the drawing using the select from drawing button.

The assumption is that pipes in a group have similar properties with respect to pipe breakage. These properties would include similar age, material, laying condition and loading and period of break records. It is usually best to create selection sets of such pipes before starting the pipe break analysis. Name the group with a label that reflects the pipes in the group. If a pipe is not assigned to a group, its individual break rate will be used as the scaled break rate.

The dialog consists of a list pane on the left that displays all of the pipe breaks that have been created for the current hydraulic model and the detail pane on the right that displays the pipes that are included in the group that is currently highlighted in the list pane, along with the following controls:

• New: Creates a new pipe break group.
• Delete: Deletes the currently highlighted pipe break group.
• Rename: Renames the currently highlighted pipe break group.
• Add Pipes From Selection Set: Allows you to add pipes to a group using a previously created selection set.
• Add Pipes From Drawing: Allows you to add pipes to a group by picking them in the drawing view.
