In (9b) the requirement is that the right hand end face must lie within the two parallel planes 0.08 apart which are
inclined at the theoretical angle of 75° to the datum axis `A' of the through hole.
Figure (9c) shows a component whose upper angle face, must lie between the two parallel planes 0.05 apart
which are inclined at the theoretical of 35° to the base, the datum surface. Notice that the theoretical angle in
each example is boxed.
Tolerances of location are identified and indicated by the symbols for the following characteristics.
