7.3.2 Hatching 

A cross-section must be set out and drawn in the same manner as a normal view whose parts in cross-section are hatched with regularly spaced strokes, the space between strokes being chosen on the basis of the total area to be hatched.

Hatching should not impede the clear reading of the reference signs and leading lines. Consequently, if it is not possible to place references outside the hatched area, the hatching may be broken off wherever references are inserted. Certain types of hatching may be given a specific meaning.
