Award-winning architects Paul Lewis, Marc Tsurumaki, and David J. Lewis's essential guide to section. Section, along with plan and elevation, is one of the most important representational techniques of architectural design. Manual of Section is the first book to provide a framework to describe and evaluate this fundamental design process in architecture.

Divided into seven categories of section based on extensive archival research:
- Range is from simple one-story buildings to complex structures
- Features stacked forms, fantastical shapes, internal holes, inclines, sheared planes, nested forms, or combinations of each
- Includes sixty-three intricately detailed cross-section perspective drawings of many of the most significant structures in international architecture from the last one hundred years

"A must-read for all designers associated with the built environment and should surely be on the library shelves of every architecture, urban design and interior design school...the intricate drawings provided by LTL are sure to inspire all those who have the privilege of cracking the spine of this amazing reference." --Spacing

In addition to the incredible cross-section drawings, the book includes smart and accessible essays on the history and uses of section.

Manual of Section has become a top architecture book for architecture students and professional architects.
