Today parametric associative CAD systems must help companies to create more efficient virtual development processes. While dealing with complex parts (e.g. the number of surfaces of the solid) no CAD modeling methodology is existing. Based on the analysis of industrial designers’ practices as well as student practices on CAD, we identified key factors that(More)
3D CAD systems are used in product design for simultaneous engineering and to improve productivity. CAD tools can substantially enhance design performance. Although 3D CAD is a widely used and highly effective tool in mechanical design, mastery of CAD skills is complex and time-consuming. The concepts of parametric–associative models and systems are(More)
RÉSUMÉ. Les nouveaux modes de travail en conception de produits impliquent des collaborations de plus en plus fortes entre les acteurs et des échanges de connaissances entre des métiers d’origines variées. Des cas de conflits peuvent néanmoins apparaître. Cet article propose un protocole dynamique définissant les modalités de résolution de conflits en(More)
