An essential reference that clarifies the role of drawing in the design process. A text that has been tested in architectural studio courses over twenty-five years and two editions, Design Drawing establishes the theoretical basis for differentiating design drawing from art or drafting in its uses, techniques, and attitudes. It relates drawing to experience, context, and the design process rather than media and form. A tool for students and professionals, the book emphasizes the step-by-step depiction of reality through perspective, shadow-casting, and entourage.
