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

Overview

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

The course aims to provide in-depth knowledge of advanced geometric modeling methods, with a specific focus on the use of cutting-edge 3D CAD systems for the creation and control of parametric geometries.

It also develops the ability to model individual components, manage assemblies using different design strategies, and generate the technical documentation required for the complete definition of an industrial product, using CATIA software.

The course combines theoretical lectures with practical sessions.

Lectures are dedicated to introducing the fundamental principles required for the informed and effective use of modern parametric, feature-based CAD systems, as well as to teaching core modeling techniques aimed at representing the design intent of industrial products.

Hands-on sessions are carried out using CATIA V5 software and are designed to strengthen operational skills through guided exercises in modeling, assembly, and technical documentation.

The exam consists of two cascaded parts.

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.
