Figure 18 Placement of dimensions or notes within the section lines.

An outline section view is created by drawing partial section outlines adjacent to all object lines in the section view as shown in figure 19.  For large parts, outline sectioning may be used to save time.

Figure 19. shows an outline section view.

Very thin parts such as washers and gaskets are not easily represented with section lines, so conventional practice calls for representing the thin part in solid black. Figure 20 shows the  section of a gasket drawn as solid black.
