Learning Objectives
The course aims to develop knowledge of CAD tools and their role in the product development cycle.
At the end of the course, the student acquires both the knowledge necessary to choose the most suitable geometric modelling strategy for the specific case studied and the practical ability to correctly use parametric solid modellers based on features.
The course also aims to provide the students, through conventional lessons, seminars and exercises, the knowledge of the most innovative techniques for the manufacture by additive techniques of a physical object starting from a virtual one. The course will analyze the main Additive Manufacturing and Rapid Tooling techinques.
Students will also be trained on the possibilities offered by 3D scanning and CAD reconstruction to switch from a physical object to a virtual object.

Course program
Parte A: 3D CAD modeling
3D modelling of solid bodies and surface bodies;
Modeling constraints: geometric, dimensional and algebraic.
2D sketch: basic functions, associativity, automatic, geometric and dimensional constraints.
2D Sketch and its functions;
3D Sketch and its functions;
Support geometry: planes, axes and points;
3D functions from sketch: base extrusion, cut extrusion, etc.
3D direct functions: chamfer, fillet, mirror, etc.
Assembly functions;
From 3D to 2D drawing: dimensioning and annotations
The concepts will be illustrated and practiced by means of "Solidworks" software package
