The purpose of the course is to give students all those tools that allow him to read, represent, analyze an architectural element in its various aspects (metric, structural, formal, etc.) according to an approach scientifically controlled as much as possible.

One of the main objectives of the Course is to give students the fundamentals and skills necessary to build and manipulate various models (geometric, graphic and computer) of an architectural object, the student is called to grapple with the problems associated with the survey and representation of a historical architecture building. On it, everyone will have to experiment with the various graphic and computer techniques acquired, as well as apply, in a controlled form, the various detection procedures.

Geometry of Representation - In this disciplinary area, the course intends to provide the student with the tools for in-depth study of the specific issues relating to the survey of architecture. In particular, it will focus on 3D modeling and the analysis of surfaces that recur in architecture.

Architectural Design - Here, too, some theoretical topics already addressed during the first two years of the course will be resumed and explored. This theoretical part will be accompanied by some application-type activities that will provide the necessary support in the progress of the survey work.

Architectural Survey - The student's greater theoretical awareness and practical ability allows in this third year to tackle the typical problems of architectural and urban survey. In recent times, this discipline has gained a leading role both in the historical-architectural culture and in the training and professional practice of the architect under the pressure of many factors: the growing need for the protection of architectural heritage; the increasingly recognized formative validity of the discipline; the growing interest in the renewal and redevelopment of historic centers and the urban environment.

It seems important to reiterate that the term Survey not only indicates the simple operation of measuring and graphical restitution of an artifact, but on the contrary that complex of operations that through the observation, analysis and representation of all the components of the architecture ( from the dimensional ones to the geometric ones, from the structural ones to the constructive ones) allow to grasp the intimate essence of the architectural or urban element being studied.

From this point of view, the survey assumes the role of a scientific discipline of a cognitive / formative nature capable of penetrating within this complex reality, becoming the basic tool for all those "reading" and "graphic transcription" operations aimed at heritage architectural, whether they are oriented towards historical knowledge, documentation and also towards conservation and restoration operations.

From a theoretical point of view, the knowledge already gained in this regard will therefore be integrated into the visual survey with what is necessary for the setting of a scientifically correct survey. The attention will be focused in particular on setting up a survey project, on the difference between direct and instrumental survey, on problems related to planimetric and altimetric survey (construction and control of polygonals, trilaterations and triangulations, forward intersection). As regards the application part, it will focus on the complete visual survey of a building and the setting of the relevant survey project. This framework therefore includes the creation of a certain number of graphic and computer drawings, which reflect the student's training path and testify to the achievement of the set objectives. As in the past year, however, these papers must be understood as the synthesis of various activities (ex cathedra lessons, computer lessons, classroom or outdoor exercises); the student must also continue to record all these experiences, in the form of notes and drawings, in his personal notebook which must be kept up to date and in order to be shown if the teachers request it.

The topics that will be addressed in this part of the course must be included in this framework:

• The history of architectural survey

The role played by surveying in our past will be analyzed in order to investigate the variation of concepts, methodologies and tools. The historical analysis will start from classical antiquity to continue through the Middle Ages and the Renaissance up to the great detectors of the nineteenth century.

Some significant examples of the history of Urban Surveying will be examined: Forma Urbis Romae, Plan of Imola by Leonardo da Vinci, Decsriptio Urbis by L.B. Alberti, the plans and views of Rome by Bufalini, Falda, Fuga Tempesta, and the plan of Rome edited by G.B. Nolli.

Will also be treated: Elements of the History of Cartography, Ancient Metrology, relationship between ancient units of measurement.

• Survey methodology

The theory of measurement, the precisions and the rules to be observed when taking measurements.

Direct survey: general problems, tools and techniques of use, traditional methodologies.

Instrumental survey: tools and techniques of use and methodologies.

Photogrammetric survey: elementary photogrammetry, Will also be treated: Elements of the History of Cartography, Ancient Metrology, relationship between ancient units of measurement.
