Mechanical drawing and CAD (5cr)

Evaluation scale

1-5

Objective

Students will learn to read mechanical drawings and be familiar with the standard symbols used in mechanical drawings. They will also be competent in independently making 3D models, quality product and assembly models, as well as assembly and component drawings. The course provides students with the readiness to create drawings of diagrams, for example for hydraulics and pneumatics, and layouts. In addition, students will learn about the modelling of designer products and CAD in a business environment.

Students will understand the operation and methods of a PDM-system (Product Data Management).

Consideration of sustainable development and recyclability in design

Content

- Theory of mechanical 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 complete given assignments using the Solid Edge 3D-CAD programme.

PDM-systems and it's functions are essential part of this course. Students will understand the operation and methods of a PDM (Product Data Management) system.

The content takes into account national and international standards (SFS, EN and ISO)
