Book excerpt: Kasprisin and Pettinari (Kasprisin Pettinari Design: Architects and Urban Planners, Seattle) present their concept of "visual thinking," which involves drawing three-dimensional renderings as a means to create environment-friendly architectural designs in urban areas. They take the reader through the design process: principles, elements, techniques of drawing; visualizing place as context; scaling; phasing; and how to involve the public in the design. Four detailed case studies and over 300 drawings illuminate the reality behind the theory. Annotation copyright by Book News, Inc., Portland, OR
