Groups of pipes and junction can be named for later recall. This is done using the Group Tools on the Edit menu. Groups may have subgroups, and pipes and junctions may be members of multiple groups.
To create a group select the pipes and junctions you want in the group, then select Edit/Groups...Create. Specify a name for the group, click OK and the Group Manager will be displayed showing the pipes and junctions in the group. Group Manager can also be used to add or remove pipes and junctions from an existing group, rename a group or delete a group.
After you've created a group you can easily select it by going to Edit/Groups/Select...then select the group by name.
Group selection appears through our AFT software; in Output Control/Display Pipes & Junctions, Select Graph Data/Profile Along a Flow Path, and Global Edit as examples, and is a great way to speeding the selection of objects.
