ARTICULATION DIDACTICS
The course will be divided into theoretical lessons and practical exercises interconnected with each other that will be checked periodically and delivered during the examination. In addition, it will be applied to a case study, to be processed individually, which will allow the assessment of knowledge and skills acquired by the candidate.
METHOD OF COMPLETION OF THE EXAMINATION
Oral presentation of the topics covered during the course;
Exercise tables (format A3);
Representation of the theme of the year (A2 format tables): Method of double orthogonal projections, Assonometry, Perspective
