Teaching Methods

During the first five sections of the syllabus the lectures are expository of the concepts, rules and standards; these classes also serve to introduce the work to be done in practical classes. The last two sections of the program are worked only in lectures that start to include exercises for the application of those concepts.

In the practical classes, students perform three different types of exercises: i) multiview drawings of parts from virtual models, ii) isometric drawings from multiview drawings iii) CAD three-dimensional models of parts represented by isometric drawings.     

Learning Outcomes

The technical drawing is a form of graphic communication for the transmission of information about the shape, size, material and function of a physical entity. Like all forms of language has rules, contained in standards whose application preteds to avoid misinterpretation and facilitate their realization.

The learning objectives of this course are:

LO1 - Promoting students' familiarity with the rules of multiview drawings;

LO2 - Develop the ability to interpret multiview drawings by conducting isometric drawings;

LO3 - Promoting familiarize students with the concepts and rules concerning indication of dimensions, tolerances and surface state;

LO4 - Promoting familiarizing students with the representation of piping and control instruments;

LO5 - Develop the ability to perform freehand sketches.

LO6 - Develop the ability to use CAD programs for solid modeling.
