3D-CAD (3cr)

Objective

After completing the course, the student is able to model 3D representations of products, sheet-metal components, and both sub-assemblies and main assemblies. In addition, the student can create manufacturing drawings and assembly drawings using a CAD system.

The student shows familiarity with the fundamental principles of technical drawing and is able to interpret mechanical drawing symbols and notations fluently. The student also takes manufacturability into account in their design work, which in turn strengthens their understanding of the product life cycle and the role of sustainable development throughout the product’s lifecycle design.

Content

-Theory of technical drawing
-3D modelling and general theory of modelling systems
-3D modelling of products and assembly models
-Drawing planes and sheet metal designing
-Diagrams and their standardised symbols

Students will do exercises using 3D CAD software.
