drawing apparatus for the preparation of technical drawings has a support for a drawing board on which paper may be attached . the support defines a frame surrounding the board which frame includes an upstanding lip for engagement by drawing instruments . front , rear and side walls depend downwardly from the frame , and flare outwardly somewhat so that a series of apparatuses may be stacked for storage , with one nested partially within another . the lower edge of each side wall defines shoulders arranged so that the drawing surface may be disposed at one of three different angles to the horizontal when placed on a support surface , with that surface engaging different parts of the side walls . the frame may include an open - topped recess for holding drawing instruments , which recess will be closed by the next apparatus up , in a stack of such apparatus .
