content: A section liner is an instrument for drawing closely spaced parallel lines, such as appeared in cross-hatching. In this example, a metal crosspiece attaches to the base of a plastic triangle. The separation between the crosspiece and the adjacent side of the triangle is controlled by the metal mechanism, which may be set for hundredths of an inch or for millimeters.
