The main issue: Geometry and Graphics, or the Ghost and the Ghostbuster

As Architecture concerns the shape of the built environment of every day life, teaching in the field of graphic representation means dealing with the most specific language that our students have to learn. Avoiding any formalistic drifts, in fact, although Architecture is not only a three-dimensional entity, but also a complex system including several physical and symbolic parameters, either visual or non-visual, under no-circumstances it is possible to achieve it without a three-dimensional consistency. That is to say, as in the true architectural world all the mentioned aspects converge in a "physical shape", so in the architectural representation field all the parameters related to those aspects have to converge in a "graphical shape". And since this graphical shape must be consistent with the architectural space it aims to represent, it is easy to see how important the role of the "geometrical knowledge is". Then, we have just mentioned the basic skills in which especially the first-year students have to improve, in order to understand and to develop the architectonic configurations: "Geometry", concerning the theoretical knowledge and the appropriate use of the spatial properties; and "Graphics", concerning the theoretical knowledge and the appropriate use of the visual tools. Sometimes I like to tell my students that Geometry and Graphics are connected as well as the "Ghost" and the "Ghostbuster" are.
