Technical Drawing

None.

  In classes, the expository method is used in the teaching/learning process of fundamental knowledge about technical drawing. Complemented by exercises on the subjects taught with a discussion of solutions.

  Objectives: Provide fundamental concepts that allow students to read, understand, interpret and create drawings and technical schemes, in orthogonal projections and in perspectives. It is also intended that they become aware of the main international standards associated with Technical Drawing and that they have knowledge of the latest 2D computer-aided design programs.

    Generic skills: Promote the exchange of ideas and discussion of problems and solutions; Develop self-learning habits and organization.

     Specific skills: Know how to interpret and create drawings and technical schemes, either using traditional means or using the latest 2D computer-aided design programs.
