What are the varieties of section, and what effects do they have on form, space, material, and program? How do architects employ a combination of section types to produce specific qualities in a building? How does section function as a tool for both revealing and generating spatial relationships?

Manual of Section explored these questions and others, providing a conceptual and practical framework for understanding this key technique of architectural representation and design. Paul Lewis, Marc Tsurumaki, and David J. Lewis have developed a new typography of section, demonstrated through 63 intricately detailed sectional perspectives of some of the most important international buildings from the last hundred years. Each drawing, based on extensive research and study, is accompanied by an analysis of how section is central to that building’s design.
