Oblique Projections, Continued
Cabinet projections are oblique projections where the receding axes are
drawn at any angle with the horizontal but usually drawn at 30° or 45°. The
full scale of the receding axis distorts the projection and requires
foreshortening to look more natural. You may use any oblique ratio (two to
three or three to four) but a one to two (one half) ratio is more common.
When you reduce the scale by half, it is called a cabinet projection. The
term cabinet drawing comes from drawings in the furniture industry.
Figure 6-6 shows a bookcase with the receding axis reduced in scale by half.
