Figure 5.14 Examples of objects having oblique surfacesD. Hidden Surfaces
To describe an object with complex internal features
completely, a drawing should contain lines representing all the
edges, intersections, and surface limits of the objects In any
view there will be some parts of the object that can not be
seen from the position of the observer, as they will be covered
by station of the object closer to the observer’s eye. The
edges, intersections, and surface limits of these hidden parts
are indicated by a discontinuous line called a dashed line. In
