Similarly, we can highlight connections on an area of the board and route them independent of
the rest of the board. For example, right depress the mouse and drag a selection box around
the left half of the board and then type ‘route 10’ to complete open connections in that area.
Autorouting an area of the board
You may notice that this has left a couple of ratsnest lines or has not completed all of the
connections. We could try to resolve this by issuing clean, filter and more route commands, but
for our purposes it’s easier to simply revert back to a ‘whole-board’ scenario and then
