Integrated design and virtual development of mechanical products
Learning outcomes of the course unit
To promote a multidisciplinary and top-down view of product design by stimulating
critical analysis of mechanical devices.
To directly experience team work.
To develop the capability to design, write and present tech reports.
To develop hands-on competence in the use a professional CAD software by using
it within project work.
Course contents summary
