It should first be noted that Rule 32(2)(d) and (g) also applies to text matter on the drawings.

For indications of the type "section on AB", see X, 7.3.1.

The drawings must not contain text matter, except, when absolutely indispensable, a single word or a few words.

Where text matter is deemed indispensable for understanding the drawing, a minimum of words should be used, and a space free of all lines of drawings should be left around them for the translation.

As regards the justification for text matter on drawings, see C-II, 5.1.
