When running the panel Wizard, two layer(s) can be optionally created: Score and Outline.
Add Scoring Lines (V-cut): Contains only horizontal and vertical lines used for scoring your PCB's in a panel. Scoring works well and is economical for PCB's with rectangular shapes.
Add Outline Layer: Primarily used as a reference and contains the Panel and Job Outlines.
All of these Panel Wizard options (above) can be performed after the Panel has been created.
