Mechanical Drawing and CAD (5cr)

Objective

The student learns to read mechanical drawings and is familiar with standardized mechanical drawing symbols and notations. The student learns the fundamentals of 3D product modeling and is able to independently produce high-quality part and assembly models as well as assembly and component drawings. Based on the course, the student also gains the ability to produce schematic drawings—such as hydraulic, pneumatic, and layout diagrams. In addition, the course covers the modeling of design-oriented products and the implementation of CAD design in an industrial environment.

The student understands the operation and methods of a product data management (PDM) system. The student learns to incorporate design-for-manufacturing (DFM) principles and full lifecycle requirements into the design process. Considerations of sustainable development, recyclability, and material efficiency are also included as integral parts of the 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 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)
