The two-dimensional drawing with plan layout, elevation, and section is a necessary prerequisite for all building. Perspectives help to give three-dimensional expression to the architect's ideas. In order to convey architecture and to build it, drawings at a reduced scale are mandatory, for the architect as much as for tradesmen and clients. This book recounts the historical development of architectural drawings and thus provides an insight into the fascinating world of this medium. It not only shows plain technical drawings but mainly focuses on impressive inventions of almost artistic quality that surprise again and again. It thus is a convincing appeal to constantly renew ways of drawing architecture and thereby to imagine future worlds.
