B6365 - Computer Aided Yacht Desing

Learning outcomes

The course aims to provide the necessary foundations for understanding the main characteristics of the modern Computer Aided Design (CAD) programs and for the correct use of these programs in the geometric modeling of yachts and boats in general. The course consists of a first part dedicated to ensuring students learn the basic rudiments of Industrial Technical Design. In the second part of the course, the topic of the Computer-Aided Design software packages are addressed and the main methodologies used in modeling, modification, coordinate transformation and visualization of curves, surfaces and solids of interest to the nautical sector are described.

Course contents

The industrial technical drawing and the main reference standards. Assembly and part drawing. Representation of Ccommercial components on drawings. CAD systems: general information, use in modern industry and product development cycle, geometry management systems (Boundary Representation, B-Rep) and Constructive Solid Geometry (CSG). Bezier Curves and Surfaces, B-Splines, NURBS. Parametric CAD. Notes on rendering methods. Impact of manufacturing technology on the components' design and modelling.

Exercises with progressive complexity on the use of CAD systems. Solid and surface modelling. Modeling of components for the nautical and marine engineering, including propellers.

Teaching methods

The course includes a part of theoretical lessons in which the main concepts related to industrial technical drawing are introduced to students. In the following, the main characteristics of CAD systems are explained in order to understand the numerical foundations that underlie the representations of the components in software. A large section of the course is dedicated to practical exercises carried out on PCs in which CAD systems are installed for the modeling of bodies of increasing complexity, assemblies, 2D construction drawings. At the end of the introductory phase in which the students familiarize themselves with the CAD systems, exercises are proposed relating to the modeling of components of interest for the nautical and industrial sectors in general.

Assessment methods

The final exam aims to ensure that the students have achieved sufficient mastery of the use of CAD systems for rapid placement in companies or design studios. The final exam, also wants to verify that the fundamentals of industrial technical drawing have been learned which are the prerequisite for creating correct CAD drawings from the point of view of compliance with regulations. To this end, the exam involves the discussion of a project assigned to students which involves the use of CAD to model components or simple assemblies of interest to the nautical sector. The discussion is followed by three theoretical questions to be answered orally to verify the learning of the theoretical contents of the course. 15 points are assigned to the discussion part of the project, while the remaining 15 points are assigned to the theoretical part (5 points per question): the final grade is given by the sum of the scores obtained in the two parts. Honor is awarded in case of particular mastery of the contents demonstrated by the students.

Teaching tools

To support teaching, course notes are made available to students on the UNIBO repository. Furthermore, the drawing tables that are proposed during the course are shared, including the modeling exercises. Part of the exercises are carried out using CAD systems in  computer laboratory.
