Keep Wires Connected to

Splits paths, pathsegs, and via vertices coincident with a selected vertex. These are split as a set.

• All wires and vias: Maintains pathseg-to-pathseg and pathseg-to-via connections during split.
• Spine wires only: Maintains connections to spine pathsegs but not to connecting vias when splitting a spine. This option is selected by default.
• No wires and vias: Does not maintain pathseg-to-pathseg and pathseg-to-via connections during split.

Keep wires connected to shapes

Maintains connection with shapes, such as pin figures, rectangles, polygons, and MPP, coincident with the selected vertex during the split operation. This check box is selected by default.

Lock Unselected Vias

Locks the vias that are not selected while splitting a wire. By default, this option is disabled. It is enabled only when the All wires and vias option is selected from the Keep Wires Connected To field.
