An apparatus and method for teaching skills related to the preparation and interpretation of mechanical drawings, including a box with two opposing, hingedly-attached panels that open to form a pair of work surfaces, a set of cards depicting isometric views and orthographic projections, a set of cubes, a set of pieces for use in constructing isometric views and orthographic projections, a timer, and dice. The interior of the box may contain a plurality of compartments dimensioned for storing the components of the apparatus, a turntable and a slot for holding a card. The apparatus enables the user to practice a variety of drawing-related skills, including: using the pieces and cubes to construct two-dimensional and three-dimensional representations, respectively, of an object represented on a card; using the pieces to construct two-dimensional representations of a three-dimensional object constructed with the cubes; and preparing isometric views from orthographic projections and vice versa.
