Learning Objectives
The course aims to provide the students with the bascic knowledge of CAD tools(and more in particular Computer Aided geometrical modeling) and of their role in the product development process.
At the end of the course, students will be able to appropriately chose the 3D modeling strategy more suitable to a given mechanical part or assembly and to put it into practice by using parametric and feature based solid modeling software packages.
Prerequisites
Knowledge of technical and industrial drafting standards.
Ability to extract from a technical drawing geometric, functional and technological information.

Type of Assessment
The exam consists in the development and presentation of a design case study carried out by means of Solidworks software package selected according to the teacher's indicatons.
And oral discussion about the course topics is also requested.
