Where figures drawn on two or more sheets are intended to form one whole figure, the figures on the several sheets shall be so arranged that the whole figure can be assembled without concealing any part of the partial figures.

Partial figures drawn on separate sheets must always be capable of being linked edge to edge, that is to say no figure may contain parts of another.

The case may arise where the parts of a whole figure are drawn on a single sheet following a layout different from that of the whole figure, e.g. a very long figure divided into several parts placed one above the other and not next to one another on a sheet. This practice is permitted. However, the relationship between the different figures must be clear and unambiguous. It is therefore recommended that a scaled-down figure be included showing the whole formed by the partial figures and indicating the positions of the sections shown.
