Freehand architectural drawing. Urban sketching

This book was written for the students of the international study course at Sapienza University. It illustrates the crucial preliminary procedures required when using drawing to gain information about architectural and urban heritage. In particular it explores the problems regarding the geometry, perspective, proportional and perceptive relationships of built heritage; it also demonstrates the use of manual graphic techniques by presenting numerous real life and freehand drawing exercises, with a special focus on colour. The book is intended as a reference for both professors and students because it not only deals with geometric codes that help to knowingly represent architecture and the city, especially architectural space, but also because it suggests the best traditional and innovative instruments, methodologies and graphics on a case by case basis
