Protractors; rulers. -For laying off courses, a circular protractor A is used in combination with a straight-edge B, the straight edge having a projecting portion C so disposed that the centre of the protractor lies over the edge of the straight-edge when its circumference touches the portion C. An arm D may be clamped to the protractor so that its end may guide the protractor along the straight-edge.
