Sufficiency in geometry and linear algebra.

Computer aided design aims at provide to the students the knowledge regarding the design process and 3d modelling from a theoretical and practical point of view. The course includes the teaching of the 3D modelling software Catia V5, with particular attention to the surface modelling in the Generative Shape Design module.

Overview

Computer aided design aims at developing engineering design skills with a particular focus on the proficient use of modern CAD-integrated analysis tools.

Learning Outcomes

After the course the student should be able to

* acquire detailed knowledge and understanding of the most recent advances in 3D computer aided design.

* know the fundamental building blocks for creating parametric geometry.

Theoretical and practical lessons

The exam consists of two cascaded parts (maximum overall duration: two hours).

The first part is closed book; the student is asked to illustrate some theoretical topics.

The second part, that starts when the student has completed the first part, consists in modelling, using CATIA, a given mechanical/aeronautical component and outputting the detail drawing.
