"If the length of a line is extended to touch the horizontal and vertical planes, it will produce piercing points. Extend the line in the front view until it crosses the axis between the horizontal and frontal planes, and then determine where in the horizontal plane the actual piercing takes place. Piercing may also occur outside the box. Extend the planes to illustrate this result."
