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).
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) Read or write geometrical specifications (tolerances) in the detail drawings of mechanical systems components and select ISO fits in order to fulfil the predetermined design requirements.
Technical skills acquired in this Unit are important for course units like “Introduction to Materials and Manufacturing Processes”, “Manufacturing Processes”, “Computer Aided Design and Manufacturing” and “Project and Team Management”.
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 tolerancing - ISO system of limits and fits; geometrical tolerancing (tolerances of form, orientation, location and run-out; datums and datum-systems); tolerancing requirements (envelope, maximum material, least material and reciprocity); general tolerances; indication of surface texture.
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.

To be approved in this course unit, students cannot miss more than 25% of classes, according to Article 7 of the Specific Rules for FEUP's Students Assessment.
Final grade = 0,4 * A + 0,35 * B + 0,25 * C
where:
A - "Orthographic representation and dimensioning" (1st test);
B - "Isometric representation" (2nd test exercice);
C - "Geometrical product specification (tolerancings)" (2nd test exercice).
Carrying out the three individual evaluation exercices is a necessary condition for considering that there is a minimum number of elements that allows a correct assessment of each student.
The approval in this course unit depends on the “geometrical product specification” evaluation exercice mark to be greater or equal than 8,0/20.
It will take place an optional resit exam (it will cover one or two exercises out of three).
When the final grade is greater or equal than 9/20, information (if any) about students’ remaining work and performance can improve this grade up until two more values.
The attainment of a final grade, in the course unit, greater than 18/20 must be confirmed by a complementary test.
Not applicable
An exam at the special season (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).
An exam (according to Article 10 of the Specific Rules for FEUP's Students Assessment).
