DesignDisegno. Geometry, measure and algorithm for architecture and the city

In a design process, the drawing (Italian: disegno) of an object or a space is the act of representing that thing with the idea of knowing and modifying it, and it is an essential moment. It is an operation that requires a synthesis capable of projecting and confronting on a two-dimensional surface - physical or virtual - the complexity of the world with an idea of form. The concept of measure and measurement is therefore, for the designer, the instrument that makes it possible to make an object, architecture or an urban fact representable, abstract, knowable and therefore designable. Similarly, for the user of that space, the measurement will help to memorise, map and place him in relation to it. Mathematics and geometry have played a fundamental role in enabling this knowability. The machine of the two mirrors invented by Brunelleschi opened up the definition of the rules of perspective and performed the compression of a three-dimensional world regulated by numbers, on a two-dimensio
