The final step is to run the autorouter. It takes only a few seconds. . .

. . . to complete the design.
At this stage the tracking can be manually adjusted, perhaps to make it a little easier to etch. But we always run the checker to be certain the copper paths match the schematic wiring wiring (in case manually editing has caused a problem).

The example above was routed with typical track widths used in school. It was also routed double sided which many schools avoid because they don’t know how to successfully make double sided boards. XLD also removes unnecessary vias, places where the tracks change side away from components. When vias are present, both sides of the track have to be connected with pins or wire links. Minimising them saves assembly work. (Professionally printed pcbs have electroplated holes so via and holes automatically connect through the board – plated through-hole manufacture.)
