Descripción
Drafting tools for drawing straight parallel lines, generally consisting of ungraduated strips of wood, metal, or plastic guided along drafting boards and held parallel by wires or strings passing through the ends of the rules; may or may not slide on rollers. For a set of two attached and pivoting rulers used often as navigational aids to transfer parallel lines, prefer "parallel rulers."
