Teaching methodologies

Exposure in the classroom matter followed by practical drawings / exercises applying the acquired knowledge;
Aulas de laboratório onde é ensinado aos alunos como manipular equipamento de metrologia usado para
controlo dimensional e geométrico de peças;
CAD classes, using various modules of CAD software, promoting good practices and use of the software and
drawing organization;
Carrying out a final project with individual and group components.

Demonstration of the teaching methodologies coherence with the curricular unit's intended learning outcomes

Execution of several practical works applying the knowledge transmitted;
Laboratory activities, enabling students to the use of dimensional and geometric control equipment;
Group work with individual components, fomenting ability to work individually and coordinating the individual
work with the group;
Design in CAD where the student can apply all the knowledge acquired throughout the unit and build capacity
for future progression in the drawing area.

Assessment methodologies and evidences

Continuous assessment

20% - Test (Tolerances and surface finish)*
15% - #1 CAD application (individual)*
15% - #2 CAD application (individual)*
