Improved device for drawing boards, of the type comprising a flat and conveniently prepared general board in which there is a basic rule, movable in the sense of depth or elevation, in perfect synchronism, by means of shooting and guiding filaments, characterized essentially because at the ends of the basic rule are coupled flat plates of profiled edges with pulleys housed inside, whose edges act as a rail on the ends of the board itself, this in its corners having pieces with edge brow, which raise the filaments to make way for the basic rule.
