ISOMETRIC (PICTORIAL) PLUMBING OR PIPE DRAWINGS: Use
isometric pipe drawings for all pipes bent in more than one plane. You may
use either the single-line or double-line method. The finished drawings are
easier to understand in pictorial format than as orthographic line drawings.
Figure 4-44 is an example of a single-line isometric pipe drawing.
