ELEMENTS OF A SKETCH:
a. A legend is used to avoid cluttering up the sketch. All pertinent evidence
or items should be shown in the legend. Include therein items on the sketch which
require clarification as to name.
b. Rough sketches are normally "not to scale." If a scale is used, it must be in
conventional measurements adaptable to the scene. Steps or paces are not used.
c. For clarity, all rough sketches should include a caption as to its purpose at
the top center.
They should also show the direction of "NORTH" indicated in the
bottom center between the legend and title block. "NOT TO SCALE" should be written
at the bottom. Center the legend at bottom left, the title block at bottom right.
d. Three separate sketches are recommended to prevent photographic actions and
measurements from being cluttered.
