Author and architecture educator Frank D.K. Ching shares his unique command of visual language in this revised guide to drawing principles and techniques. Design Drawing is an innovative book-plus-CD-ROM package sheds new light on the relationship between perception, drawing, and design. He unmasks the basic cognitive processes behind visual perception and expression, incorporating observation, memory, and rendering into a creative whole, and shows how to apply "visual thinking" as a versatile tool for approaching design projects. The companion CD-ROM has been revised with 12 new modules, and an easy-to-use interface.
