7.11. Technical Drawing & CAD (Mandatory)

7.11.1. Justification ↑ Back to top

Technical Drawing and CAD is a foundational course for engineering students, as it provides the graphical language needed to communicate technical projects. Mastery of descriptive geometry, drafting standards, and Computer-Aided Design (CAD) tools allows students to represent three-dimensional objects with technical precision on a two-dimensional plane, an essential skill for the design, execution, and supervision of engineering projects. The course closes with an application to civil engineering drawings, covering the symbols and conventions used in foundation and basic structural plans.

7.11.2. Generales Goals ↑ Back to top

1. Apply national and international technical drawing standards to produce engineering drawings.
2. Develop spatial visualization skills through the study of projections and descriptive geometry.
3. Use modern CAD software tools to create geometric models and technical project documentation.
4. Apply engineering drawing conventions to civil engineering plans, including foundations and basic structures.
