Objectives of the course
The module aims to teach the basic principles of the technologies applied in CAD systems, potential for integration, and the evolution of
information systems used to support design and documentation activities.
Expected skills
Students will be expected to acquire operational skills in the use of a latest generation three-dimensional modelling system.
Students must have obtained credits in the Industrial Technical Drawing module before starting this course, and must be familiar with
the fundamental concepts dealt with in the Basic Principles of Computer Science module.
Credit 1: Computer Aided Design and Computer Aided Manufacturing (CAD-CAM)
Complementary subjects to industrial technical drawing: functional and technological dimensioning, shaft-hub connections,
representation of bearings, gears and pulleys.

General introduction to CAD systems. Hardware: systems overview, types of configurations, peripherals, graphical input systems.

Software: interactive graphics packages, two and three-dimensional systems. Physical objects, models and representations. Elements
of Computer Graphics; Image Processing. Viewing techniques. Rendering techniques. The CAD-CAM process. Issues of CAD-CAECAM

Credit 2: Elements of Computer Graphics
Parametric curves and surfaces. Bezier, Spline, B-spline and NURBS curves and surfaces; absolute and relative coordinate systems.

Introduction to basic algorithms for geometric transformations: translation, rotations and transformation of scale.

Credit 3: Geometric Modeling
2D and 3D models; wire frame, B-Rep and CSG. Modeling from geometry based to knowledge based: parametric, variational and
feature-based systems. Notes on non-rigid objects modeling.

Credit 4: Integration Methods and Technologies
Design development process. PDM systems, Digital Mock-up. Data exchange problems: the transfer of information between different
CAD systems; IGES, STEP and SAT standards.
Laboratories and/or exercises
Modeling of mechanical components by using CAD feature-based systems. Assembly of components. Documentation of components
and assemblies through two-dimensional drawing.

The teaching staff is available to students to clarify topics dealt with during lessons and practical work and to informally evaluate the
student's progress.

Exam Procedure

The exam consists of a practical test in a CAD laboratory, that takes into account also the practical work carried out during the course, a
written paper test, and if necessary an oral test. To pass the exam students have to pass both the practical test and the written one.
Students cannot take the exam unless they have completed at least 80% of the practical exercises set during the course.
