Contribution à l'analyse et à la réalisation d'un système de CAO à base de caractéristiques de forme

Abstract : Modelling represents a large part of CAD/CAM systems. The work presented in this thesis is concerned with product modelling and consists in proposing a form feature-based design system. This system has main functions : features insertion in the designed part and their management all along the product evolution (modification, removal ...) ; creation of user-defined generic features and their insertion in the form feature library. A data structure able to model form features is presented first. Then a modification management method in the design model is proposed ; it avoids re-evaluating the whole design history. Finally, interactive and convivial tools allow the user to integrate new features into the software. The last part is concerned with the computer implementation of these proposals
