On the Schematic Design toolbar, click Modify > Slice, or on the PCB Design toolbar, click Rework > Slice.
In the Slice dialog, review or select a slice width and slice behavior: whether to ripup, and which side segment to ripup.
Click to set a start point for the slice line on one side of the path or paths.
Drag the cursor across the path, then click to set an end point. The selected slice behavior is applied, and in the case of board traces, the resulting airwire segment is available for rerouting.
