Introduction of the concept of Standardization in general and of its importance in Engineering. Acquisition of deep knowledge about the representation of the nominal shape and dimensions of objects. Development of spatial visualization and technical communication skills. Introduction to the concept of Geometrical product specification (GPS). Acquisition of basic knowledge about surface development methods. Introduction to diagrammatic drawings.
At the end of the course, the students should be able to:
1) Make drawings of objects in orthographic representation and with nominal dimensioning.
2) Read drawings of objects in orthographic representation and make the correspondent pictorial representations (isometric drawings).
3) Interpret the meaning of the dimensional tolerances inscribed in drawings and determine the ISO fits that fulfils the design requirements previously established.
4) Make the developed views of polyhedral and single-curved surfaces.
Technical skills acquired in this Unit are important for course units like Mechanical Engineering Drawing, Computer Aided Design and Manufacturing and Introduction to Machine Design.
Basic notions about drafting and drawing instruments (secondary school). - Fundamentals of plane and solid Euclidean geometry (secondary school). - Elements of descriptive geometry (secondary school).
STANDARDIZATION in general and in technical drawings. TECHNICAL PRODUCT DOCUMENTATION: scales, drawing media, ISO lettering and lines. Types of projection systems. Short references to the dihedric method. ORTHOGRAPHIC REPRESENTATIONS: general principles of presentation for views, the choice of views, partial views, auxiliary views, cuts and sections. The reading of orthographic drawings. PICTORIAL REPRESENTATIONS: axonometric representations (isometric drawings). INDICATION OF DIMENSIONS AND TOLERANCES: general principles; dimensioning of angles and slopes on prisms; dimensioning of conical tapers and taper angles; dimensioning of profiles; theory of nominal dimensioning and preferred numbers. GEOMETRICAL PRODUCT SPECIFICATION (GPS): The concept of GPS, the model for geometric specification; fundamental tolerancing principle; dimensional tolerances - ISO system of limits and fits. SURFACE DEVELOPMENT. Simplified representation of PIPELINES.
Lectures are based on detailed expositions of each basic topic of the course, illustrated by the presentation of application examples.
Tutorials are based on brief presentations of complementary topics of the course, intercalated with the resolution, by the students, of exercises considered relevant and that can be found in the main bibliography of the course unit.

Students have to attend to 75% of the classes, according to Article 7 of the Specific Rules for FEUP's Students Assessment.
Final grade = 0,4 * A + 0,35 * B + 0,25 * B
where:
A - is the exercice of "Orthographic representation and dimensioning" (1st test);
B - is the exercice of "Isometric representation" (2nd test);
C - is the exercice of "Dimensional tolerances and surface development or pipelines" (2nd test).
Carrying out the three individual evaluation exercices is a necessary condition for considering that exists a minimum number of elements that allows a correct assessment of each student.
It will take place an optional resit exam (it will cover one or two exercices out of three).
When the final grade is greater or equal than 9,0/20, information (if it exists) about the remaining work developed in classes may increase this grade up to a maximum of 2,0/20.
The attainment of a final grade, in the course unit, greater than 18/20 must be confirmed by a complementary test.
According to items 9.1 b) and c), 9.2 to 9.4 in Article 9 of the Specific Rules for FEUP's Students Assessment.
According to Article 10 of the Specific Rules for FEUP's Students Assessment.
