Hidden lines
Lines not readily apparent in a view of an object are hidden lines.
Hidden
lines are evenly-spaced, short dashes that begin and end as a dash in contact
with the line from which it starts and stops. The exception being when it is a
continuation of an unbroken line.
Figure 3-8 shows hidden lines.

Hidden lines that join visible lines or another hidden line must contact the
