Teaching methods

The course proposes an operative approach divided into lectures and direct applications of the theoretical contents to a reference case study.
The design of a simple housing structure - ready-house - will be studied, following the path from the initial idea to its architectural definition.
We intend to explore innovative representation systems through three-dimensional modeling, intended as a real "construction" of the architectural object, combined with the extraction of two-dimensional technical drawings.
At the same time, a similar method will be applied to the study of an existing architecture, starting from direct survey techniques and ending with indirect survey through photo-modeling.
The survey is an instrument of knowledge of the architectural, urban and environmental reality, and the photo-modeling techniques allow the construction of a photo-realistic 3D model of the inquired object.
The course will have a double approach to representation, in which the digital techniques will be used both to create images starting from reality (shooting techniques, image management and software, etc.) and to generate digital images from 3D models, through the reverse process.

A. BASIC KNOWLEDGE OF THREE-DIMENSIONAL DIGITAL DRAWING - 20 hours -
The module aims to make students acquire the mastery and the theoretical bases of three-dimensional digital modeling methods and techniques.
It will consist of a series of lessons on the basis of the discipline with examples of the software used in the course.

B. REPRESENTATION OF ARCHITECTURAL DESIGN - 60 hours -
The module aims to provide the methodical basis necessary for the interpretation and execution of the architectural project.
The course includes in-depth study of technical drawing, and the construction of three-dimensional CAD models.
The module includes practice exercises preceded by a brief introduction.

C. SURVEY OF ARCHITECTURE - 60 hours -
The module aims to make students acquire the methods and techniques of direct and indirect survey of the architectural spaces and of the graphic representations of the architectural survey.
It includes both lectures and exercises that will allow you to connect theory to practical applications.




Assessment methods

The course ends with a scrutiny of the graphics produced by the student during the course. The preparation and presentation of practice works is needed for admission to the exam. The completeness of the documentation will be verified at the end of the course in a "final review" required for the admission to the exam.
The exam consists of a practical 3D CAD test and an oral including a graphic practical exercise.
All the tests must be taken in the same exam session.
For students who will successfully attend reviews and ongoing tests of the course, and who will take the exam in the first session (sessions of January-February 2022), the exam will consist in the public presentation and discussion of the graphics made during the course.

The evaluation grade is available on student request

B. REPRESENTATION OF THE ARCHITECTURAL DESIGN - 60 hours

The annual workshop will consist in the design of a simple housing module called "ready-house".
At the end of the course, the student will be able to produce the documentation that from the initial idea leads to the representation of the architectural project, through three-dimensional modeling.
The 3D model is a real "construction" of the architectural object, from which the two-dimensional graphics can be extracted.
The development of the project will be partly individual, and partly collective.
The course is a practical laboratory in which the knowledge of representation’s rules will be applied, and the project documents will be developed.
The material produced by the students during the workshop will be regularly shared on the Virtual platform to allow monitoring. During the exercises, reviews of the work are scheduled on the calendar.
The "annual workshop" must be developed continuously and periodically checked with teachers and tutors. In addition to the annual workshop, there are 3 ex-tempore exercises related to the theoretical lessons of 3D modeling.

C. MODULE OF ARCHITECTURAL SURVEY – 60 hours –
The exercise has as its objective the survey and the technical representation of a part of the walls of Bologna or of a city gate, obtained both through direct survey techniques and through indirect survey with digital photogrammetry applications.
First of all, the planning of the survey will be expected according to the needs and requirements of the work, integrated with visual and direct survey applications. The data of this survey phase will be represented through plans, sections and elevations. The indirect survey phase involves the acquisition of photographic data, which will be processed in digital photogrammetry applications in order to produce a photo-realistic 3D model, as well as orthophotos and consequent technical elaborations at various scales.
The exercises will be carried out both in the field and in the laboratory, where all the software for data processing will be made available. The works to be realized, which can be developed in different tables, will include the following contents:
C0. Preparatory studies – photographic survey – eidotypes with sketch collection
C1. Direct metric survey (1/50 restitution scale): - plants with measures, - plants with materials, finishes and degradations; - significant sections with measures, - sections supplemented by materials, finishes and degradations; - elevations with materials, finishes, degradations.
C2. Digital photogrammetry: - techniques for the reconstruction of the three-dimensional model: critical reports of the data processing phases; - three-dimensional textured model: external views, sections, orthogonal views of the model; - technical drawings for CAD vectorization of orthophotos, plants / sections.
C3. Summary papers: - comparisons between direct survey and digital surveys by overlapping technical documents: extracts of the significant parts and critical analysis of the results.
Delivery methods: I – ex-tempore exercises: in the classroom at the end of each test; II – autonomous exercises: to the exam. The module includes direct and indirect survey activities in the field, with applications in the laboratory.
