Multiple functions of drawings

In the twentieth century, the functions of written or spoken language were extensively studied. The functions of drawings were studied less. This was largely due to a kind of ‘verbal-centrism’ that dominated the general discussions on the mechanisms of interaction and communication. This article explores the various possible functions of drawings, focusing on architecture, urban design and planning. It initially attempts to build a typology of the different functions of drawing and, later, to discuss relevant aspects such as the relationship of each function with reality. The article concludes by dwelling on the theoretical and practical importance of this approach.
