Select a predefined path for the circuit or specify a custom path.
The circuit path can include all devices or only the farthest device. When you modify the circuit path, a custom path is created and remembered, so that you can select it later on.
All components except those in the selected circuit are dimmed in the drawing area and the Edit Path toolbar displays.
If you have modified the circuit path, you can select Custom as the Path Mode.
Notice that the value for the Length is updated on the Edit Path panel.
