Tip
Use <Ctrl-Shift-W/N> to widen/narrow the trace. You can also change the trace width
during routing by typing the desired value in the
Draw Settings
toolbar. Otherwise, trace
size is determined from the net settings. If you attempt to change to a net width that is too
big (DRC errors appear), the trace width will not change.
