Oblique Projections, Continued
When an angle of a specific degree lies in a receding plane, you must covert
the angle into linear measurements before drawing the angle in oblique
projection. Remember that in a cabinet projection, you must reduce all
receding dimensions by the same reduced scale.
Sections in oblique projections are often used to show interior or hidden
shapes. Oblique half sections where you remove only a quarter of the object
is the most common section used because it shows so much more of the
interior surface. Oblique full sections where the plane of intersection passes
completely through the object are seldom used. You may use all types of
sectional views in an oblique projection.
Figure 6-10 shows a half and full section of an oblique projection.
