Figure 9-12 Objects with inclined surfaces have at least one view where the surface is not parallel to the
projection plane. The inclined surface of this object does not appear in its true shape and size when projected
to the top and side views. It instead appears foreshortened. The front view shows the inclined surface in its true
length but does not show the surface’s true shape. To see the true shape and size of an inclined surface, you
must draw an auxiliary view. Auxiliary views are discussed in Chapter 12.

Figure 9-13 Lines in a multiview drawing represent edges of surfaces, intersections between surfaces, or
limiting edges of round objects.
