- Contents
- This teaching module provides the basic skills necessary for the correct realization and interpretation of technical drawings in the mechanical/industrial sector. The main content concerns: standardization and unification, methods of graphic representation, geometric dimensioning and tolerancing; materials; main unified mechanical components and their representation; relationship between shape, function and production process; reading of diagrams; use of CAD software for two-dimensional drawing.

Further educational material including slides of the lessons, texts and solution of the proposed exercises, tables, videos and more is available through the Unistudium platform - Educational objectives
- The teaching helps to train the student on the methodological-operational aspects of engineering sciences in general and mechanical engineering in particular; provides the basic methods and tools for the design and representation of components, systems and processes; introduces the methodological aspects of modeling, design and the links between the above topics.
The main objective is to provide the students with the foundations for the correct realization and interpretation of technical drawings in the industrial/mechanical sector.
• Understanding the basic principles of representation and ability to choose the most appropriate method;
• Understanding of the basic principles of geometry applied to representation methods;
• Knowledge of standardization and unification; ability to search, read and interpret international standards
• Knowledge of the various types of technical design (assembly drawing, part drawing) and of the elements that make up them (views, section views, dimensions, tolerances and annotations)
• Knowledge of the main classes of unified mechanical components and their conventional representation (threads, nuts, bolts, screws, engineering fits, bearings and spur grars); ability to independently identify these components from catalogues/standards
• Ability to interpret the prescriptions about dimensional, geometric tolerances and surface finish
• Ability to interpret the drawing in relation to the functional and manufacturing requirements
• Ability to read and interpret diagrams
• Proficiency with computer-assisted 2D drafting. - Prerequisites
- Preliminary knowledge of geometry (e.g. points at infinity, concept of distance, planar transformations, conic curves) and basic computer skills are strongly recommended.
- Teaching methods
- The teaching consists of:
• Classroom lectures which address the theoretical topics of the module;
• Practice sessions consisting in computer-assisted drafting.
All the teaching material– e.g. lecture slides, exercises, tables, videos and other content – is available through the Unistudium platform - Other information
- Further information is available through the Unistudium platform. Specific questions can be asked to the teacher at the end of each lesson; in person or on-line meetings (via MS Teams) can also be arranged upon request.
- Learning verification modality
- The exam consists of two parts:
• A theoretical test consisting of a multiple-cloze quiestionaire administered on the LIbreEOL platform (duration 20');
• A practical test consisting of the execution of a technical drawing using 2D drawing software (duration 1h 30' approximately).
The theoretical test is aimed at assessing the theoretical knowledge of the topics addressed in the module; the practical test to evaluate the ability of the student to produce digital drawings compliant with the international standards.
Unless otherwise specified the two tests take place the same day, one after the other. To pass the exam a minimum score of at least 18/30 or higher needs to be attained in both tests, and the final mark is the average of the marks obtained in each test. - Extended program
