Eleven Exercises in the Art of Architectural Drawing [EPUB ebook] 
Slow Food for the Architect’s Imagination

This book deals with the critical nature and crucial role of architectural drawings. A manual which is essentially not a manual; it is an elucidation of an elegant manner for practising architecture. Organized around eleven exercises, the book does not emphasize speed, nor incorporate many timesaving tricks typical of drawing books, but rather proposes a slow, meditative process for construing drawings and for drawing constructing thoughts. This is an indispensable reference text and an effective textbook for students seeking to advance their appreciation of the nature and exercise of architectural drawings.
