Architecture and the Lost Art of Drawing - parallels a theory that drawing of any sort can enhance one's thinking process when searching for solutions to seemingly unsolvable problems. Making a plan... in graphic terms... block diagrams... flow charts... ie: a graphic list ... showing what fits and what doesn't... taking a mental overlay and translated to a visible pattern to discover what is not seen at first reading... (the negative spaces) - not just in graphic terms but what one may not have thought of in the original plan). These hand to eye to hand tools develop the connections in the brain for problem solving and creative thinking.
