This book contains key texts on the theory and practice of architectural design tools (drawings, models and computers) from antiquity to the present. In this unique compendium of primary sources, the remarkable developments of the field are catalogued--emphasis on Euclidean geometry in the middle ages, introduction of perspective in the renaissance, development of descriptive geometry in the enlightenment and constructivism in the early twentieth century. Similarly, over the past half century, the predicative role of architectural representation has undergone a profound transformation motivated by computers. Brought together for the first time, this reference is especially suited for students of architectural representation and design courses.
