Selection sets are user-defined groups of network elements. They allow you to predefine a group of network elements that you want to manipulate together. You manage selection sets in the Selection Sets Manager.

HAMMER CONNECT contains powerful features that let you view or analyze subsets of your entire model. You can find these elements using the Network Navigator (see Using the Network Navigator ). The Network Navigator lets you choose a selection set, then view the list of elements in the selection set or find individual elements from the selection set in the drawing.

In order to use the Network Navigator, you must first create a selection set. There are two ways to create a selection set:

• From a selection of elements--You create a new selection set in the Selection Sets Manager, then use your mouse to select the desired elements in the drawing pane.
• From a query--Create a query in the Queries Manager, then use the named query to find elements in your model and place them in the selection set.

The following illustration shows the overall process.
