B6365 - Computer Aided Yacht Desing

Learning outcomes

The course aims to provide the necessary foundation for understanding the main features of the most modern Computer-Aided Design (CAD) programs and for the correct use of such programs in the geometric modeling of yachts and boats in general. The first part of the course is dedicated to ensuring students learn the basic rudiments of Industrial Technical Drawing. The second part of the course addresses the specific topics of Computer-Aided Design and describes the main methodologies used in the modeling, editing, coordinate transformation, and visualization of curves, surfaces, and solids relevant to the nautical industry.

Course contents

Overview of the main concepts of industrial technical drawing and the main reference standards (ISO). Part drawings, assembly drawings, and exploded views. Standardized components. CAD systems: general information, use in modern industry and the product development cycle, geometry management systems (Boundary Representation, B-Rep) and Constructive Solid Geometry (CSG). Bezier curves and surfaces, B-Splines, and NURBS. Parametric CAD. Overview of rendering methods. Impact of manufacturing technology (subtractive, formative, and additive) on component modeling. Progressively complicated exercises on the use of CAD systems. Solid and surface modeling. Modeling of components relevant to the nautical industry, including hulls and propellers.

Teaching methods

The course includes a theoretical part introducing students to the main concepts of industrial technical drawing. The main features of CAD systems are then explained, enabling students to understand the numerical fundamentals underlying component representations.

A wide part of the course is devoted to practical computer exercises using CAD systems to model bodies of increasing complexity, assemblies, and 2D construction drawings. Following the introductory phase, during which students familiarize themselves with CAD systems, exercises are offered on the modeling of components relevant to the nautical and industrial sectors in general. The course is divided into Module 1, which covers the modeling of solid bodies and assemblies, and Module 2, which covers the modeling of surfaces and hulls.

Assessment methods

The final exam is designed to ensure that students have achieved sufficient proficiency in the use of CAD systems for rapid entry into companies or design studios. It also verifies that they have mastered the fundamentals of industrial technical drawing, which are essential for producing CAD-based drawings that comply with regulations.

To this end, the exam involves using CAD to model hulls, components, and simple assemblies relevant to the nautical industry. The completion of the drawings is followed by an oral discussion of the completed drawings, in which the findings are discussed in light of the theoretical content of the course. Honors (30 lode) are awarded for students demonstrating exceptional mastery of the course content.

Teaching tools

To support teaching, course notes are available to students on the website: virtuale.unibo.it

Furthermore, the drawing presented in class are shared, including the modeling exercises. Some of the exercises are carried out using CAD systems available in the on-site computer lab.
