ABSTRACT:
An educational device for aiding in the projection of views of an object. The device includes a first half-hexahedron composed of a bottom panel, a first vertical panel and a second vertical panel. The panels are perpendicular to one another and together define a corner space for accommodating an arbitrarily configured object supportable on the bottom panel. There is further provided a second half-hexahedron composed of a transparent top panel, a transparent third vertical panel and a transparent fourth vertical panel. The panels of the second half-hexahedron are perpendicular to one another and together define a corner space. The second half-hexahedron is removably positionable on the first half-hexahedron such that the first and the second half-hexahedrons form a complete hexahedron. Grid markings are provided on the three panels of the first half-hexahedron and on the three panels of the second half-hexahedron. The grid markings divide the panels into rectangular elements alignable with the object along imaginary orthogonal projection lines for imaginarily forming projected views of the object on the three panels of the first half-hexahedron and on the three transparent panels of the second half-hexahedron.
