Drawing analogies proposes an innovative way of drawing by means of which we can go from observing an existing architectural model to a design idea inspired by the same model. Using exclusively free hand drawing, the author presents a series of cases referring to urban contexts, historical and contemporary architecture and natural landscapes. The method involves four operative phases: observation, analysis, abstraction and analogy. To demonstrate the practical use of the method of the four phases, some of the author's projects are presented, with an analysis of the analogical sources that inspired them.
