Innovation in MCAD Education toward Competency Development using Negative Knowledge:   From Theoretical Framework to Practical Implementation

Ferruccio Mandorli, Harald E. Otto, Polytechnic University of Marche

Abstract. Nowadays mechanical computer-aided design (MCAD) systems are utilized extensively and on a broad base in the domain of industrial engineering. Those MCAD systems are used to create geometric models and virtual prototypes in order to support designers during decision-making activities, while also being used for product documentation purposes. The spread of MCAD systems within the mechanical engineering industry has increased in parallel with their technological development. The more these systems are able to provide new functionality, the more they are used to support product development processes. Similarly, with a considerable increase in their market share, systems developers are increasingly becoming aware of customer needs and are willing to improve the systems accordingly. These days MCAD systems are complex systems which rely on geometric modeling kernels that are based on a fully developed technology, on top of which sophisticated modeling functions have been implemented in order to support different directions of geometric modeling, such as parametric/variational modeling, solid-surface integrated modeling, mesh modeling, and hybrid modeling. Individual aspects, specific to each modeling direction, are managed within these systems by means of different modeling approaches such as feature-based or direct/explicit solid modeling, surface modeling based on NURBS or sub-division surfaces, and mesh reconstruction from clouds of points.
