(c) Three-point is when none of the object's surfaces (height, width, and depth)
are parallel to the picture plane (fig 2-10C).
(5) The Army Correspondence Course Program (ACCP) offers the subcourse "Draw
Subjects in Perspective" (SS 0526). This subcourse offers a more in-depth explanation on
b. Structure, the second quality of form, refers to how the parts make up the whole.
Some objects are simple forms, while others are more complex. A drawing, whether simple or
complex, must be broken down into its most basic forms, and put together in their proper places.
Paying attention to structure sets up spatial relationships which are the foundation of other steps
of the basic procedure (fig 2-11).
(1) Spatial relationships refer to the space taken up by an object and where these
objects are placed in the overall subject. A rule in visual reality is that no two forms can occupy
the same space at the same time.
