DETAILS BEHIND THE CUTTING PLANE
All the details behind the cutting plane visible after the cutting must be drawn as
simple orthographic view. Fig 4.16 shows an object pictorially with front part
removed thus exposing the inner details. A sectional front view of the cut surface
without the visible features, as shown in the figure, should never be used. Correct
sectional view is that which is showing all the visible edges and surfaces behind the
cutting plane in addition to the cut- surface. However, edges and surfaces which
remain hidden even after the cutting are not shown with the help of dashed lines in part
of the view which is in section. Usually dashed lines in a sectional view
complicate the view, as shown in Fig. 4.15, and do not add any information; the view
without these becomes simple, less time-consuming to draw, and more easily readable,
as shown in the same figure.
