When you route fibers in the Wiring diagram, you first choose a circuit to route from the Circuit diagram or from a report. The components and ports in the Wiring diagram for the selected circuit highlight when you choose a route tool. Highlight allows you to identify the ports in the selected circuit. You can change the highlight color in the System Appearance page of the Creo Schematics Options dialog box.
