cally, it is a mix of parallel and perspective systems. Such drawings are often made by designers who may sketch well but have not learned the special skill of design drawing. Such drawings emphasize individual objects but do not consider the total image of space. Often individual objects are drawn without any overlap, omitting a powerful spatial cue. The second problem, that of drawing some objects incorrectly, is the result of not knowing how to structure all elements with perspective as an aid. This is a prevalent problem with designers who otherwise may handle perspective well but do not know how to handle certain constructions. A third problem is drawing the space or elements in the space too deep. This results in a room that looks either tunnel-like or too large. By control of the cone of vision and the placement of vanishing points this can be corrected. The sketching method proposed here makes accurate design drawings easily constructed. Perspective constructions are selected to deal simply with scale and with the multiple axis problem. The unique feature of this system is that it combines several constructions into a single coherent system. As in any perspective system, this system is a structural approach.
