The Designer-Workbench project aims at transforming the classical industrial modeling and design paradigm into its virtual analog using state-of-the-art three dimensional I display technology, data gloves and spatial tracking. This paper outlines the fundamental tools and design paradigms required for the implementation of this modeling envirornment and demonstrates the usablility of virual environments (VEs) for simulation of two-handed clay modeling and design tasks on the basis of non uniform rational B-spines (NURBS)
