To Shade a Mill Surface
You can shade the mill surface to highlight the mill surface in a different color. This functionality is available only at setup time (you cannot shade a surface when creating an NC sequence).
1. Click View > Visibility > Shade.
2. Select the mill surface in the graphics window that you want to shade. Creo NC repaints the screen to display only the shaded image of the selected surface.
