Abstract

L'invention concerne un procédé permettant la conception rapide et simple d'un moule flexible destiné à une plaque vitrée, au moyen d'une application CAO tridimensionnelle pour modèles solides, comprenant l'utilisation d'un modèle solide créé antérieurement. A cette fin on modifie à l'aide de moyens de modification de forme, un cadre périphérique d'un modèle solide mémorisé dans une unité de stockage de modèles solides, de manière que ce cadre périphérique corresponde à la forme de la nouvelle plaque vitrée. Des moyens de projection de paramètres modifiés permettent de projeter la modification des paramètres modifiables hérités du modèle solide existant dans le modèle solide modifié, afin d'optimiser les paramètres modifiés du nouveau modèle solide.
