Users can select objects in the 3D scene.

Make sure the pointer cursor is active (select the pointer button on the right-hand edge of the window, or press escape). Move the pointer over different objects in the scene. Metric information and values for the object currently under the pointer will be displayed in the metric information text box (located beneath the Menu Bar).

Click (with the left mouse button) on an object to select it. The selected object will have a red wire-frame drawn around it. When an object has been selected in this way, the metric information for this object is always displayed in the text box irrespective of where the mouse pointer is. (See the selected router in Figure 1-5).

The text box is updated whenever the scene is updated with the latest value for the metric of current interest. This description includes the source, name and instances of the metric, the current value and units, and the value as a percentage of the expected maximum value.

Clicking the left mouse button on another object will change the selection as only one object may be selected at a time. Selecting the background will deselect any selected objects.

An object selected in this way will affect the “The Options Menu” items and the behavior of the launched tools from the “The Launch Menu”.
