The course aims to introduce students to the scientific foundations of representation, ie the theory and applications of descriptive geometry in relation to the four traditional methods. Starting from the logical tools of geometry and their historical-critical classification, we will discuss the orthogonal double projections, the central projections (perspective), the axonometric projections and the listed projections. In addition, the design of the arcs and vaults and the theory of shadows will be exhibited within the more general context of design studies for the architectural project and for the relief by experimenting with forms of graphic communication through analogical and digital techniques.
The Descriptive Geometry course considers the following topics of study:
1) The elements of the technical drawing;
2) Geometric entities and fundamental operations;
3) The model of double orthogonal projections;
4) The axonometric model;
5) The perspective model;
6) The model of listed projections;
7) The arches and vaults;
8) The theory of shadows.
These themes will be explored also through communications related to the historical reading of geometric models and a selection of images produced in the architectural and artistic field by different cultures, especially Western, succeeded over time.
During the semester ex-cathedra classes will be held, meetings dedicated to theoretical insights, seminars carried out individually and in groups and collective reviews of the results produced during the exercises. The course is designed as a design workshop where students are asked to work together in the classroom from the first meetings. From a theoretical point of view, students are invited to deepen the lessons and to study the texts indicated in the bibliography that will be illustrated and commented in the classroom.
From a practical point of view, students will be asked to elaborate some explanatory exercises on the theoretical topics treated, in analogy to what will be done in the classroom, and to deliver the works produced to the teacher, in order to demonstrate the work at home and understanding of the topics covered. In addition to these elementary exercises, the students will make final tables - one for each projective model - in which to represent a small building chosen from those proposed by the teacher. This theme of the year will be presented in one of the first meetings of the course and will provide students with the opportunity to test their levels of learning through the application of methods and techniques previously exposed in the classroom.

Examination methods
The final interview is the synthesis of the theoretical and practical preparation matured by the student in the Descriptive Geometry Course B. The students will have to present all the works produced during the course and from this will be the verification of the knowledge and skills acquired.
Teaching methods
The topics of Descriptive Geometry will be tested by the students in the classroom with exercises that, together with those to be done at home weekly, will be delivered to the exam. To accompany the student to the realization of the weekly exercises and the final tables will be fixed regular reviews, individual and collective, through which to verify the progress of the documents and related knowledge, skills and abilities.
