2.6.2 Cutting Planes
The cutting plane(s) should be indicated by means of type H
line. The cutting plane should be identified by capital letters
and the direction of viewing should be indicated by arrows.
The section should be indicated by the relevant designation
(Fig. 2.15).
In principle, ribs, fasteners, shafts, spokes of wheels
and the like are not cut in longitudinal sections and therefore
should not be hatched (Fig. 2.16).
Figure 2.17 represents sectioning in two parallel planes
and Fig. 2.18, that of sectioning in three continuous planes.
