Summary
Transforming a design or an aerodynamic optimization into a 3D model requires the use of acquisition and/or surface modeling tools. Indeed, when aesthetics and/or hydro or aerodynamic performance are to be considered in the design of a product, geometries cannot be modeled using simple primitives used by solid CAD systems. It is then necessary to use surface modelers using complex curves and surfaces (Spline, BSpline, Nurbs, Bezier tiles...). This module starts by studying the mathematical models used and then goes on to understand the tools available in industrial CAD systems. Keywords: Catia V5, 3D Printing, CNC machining, 3D Scanner.
Educational goals
At the end of the course, the student will be able to: - Understand the theory of mathematical tools useful in 3D surface modeling - Use an industrial surface modeler (Catia V5) - Use a 3D scanner and process the obtained model - Produce an original solution that meets an imposed set of specifications - Know the key stages of the production of complex parts (3D printing, CNC manufacturing)

Pedagogy
This lesson is divided into 3 phases proposing different approaches: -Study of mathematical models of complex curves and surfaces. This first step is necessary to understand the objects manipulated in the tools available in 3D surface modelers. This study will first be done in a theoretical way, followed by tutorials using geometry creation software (OpenScad) to understand the parameterization of curves and surfaces. -Learn surface modeling methods using Catia V5. This second part will be devoted to learning modeling methods using a parametric 3D modeler. It will take place in two step. Tutorials (TEA + tutoring) on several examples first, then a creative work based on an imposed set of specifications. - 3D scanning and reverse engineering This part will deal with obtaining a geometric model from a real shape (design model or functional object) to a digital model. It will take place in two stages. Tutorials (TEA + tutoring) on several examples first, then a reconstruction work from real parts in order to validate all the knowledge acquired in this part. - Manufacturing of complex curves and surfaces This last part will be dedicated to the machining of shapes obtained using numerically controlled machines in the form of supervised work and practical realization in the manufacturing workshop. Note: the last three parts can be processed in any order to ensure the smooth running of the module and to rationalize the use of available resources.
