The instruments used in mechanical drawing may be divided into two distinct groups: first, the set of instruments, generally in a case, consisting of a compass, dividers, ruling pens, etc., and second, the drawing board, T-square, triangles, etc. To secure good results in mechanical drawing good instruments are necessary. Economy in the purchase of instruments is unwise, because drawings made with inferior instruments will be of inferior quality in technique. A good set of instruments with proper care will serve the student's needs almost indefinitely. The instruments of the second group, such as the drawing-board, etc., may, however, be of medium grade, if the cost of the very best is prohibitive.
