Product-centred Intuitive 3D Interaction for Feature-based Parametric Assembly Modelling

Feature-based parametric assembly modelling is an approach to part and assembly modelling in CAD that integrates the advantages of feature-based modelling and parametric modelling. Hence, it allows to store a high degree of product semantic. This paper presents approaches to make use of this product semantic in order to parameterise the 3D graphical interaction. The goal is to support the designer in the modelling and virtual assembly process by guiding him during the interaction. Only valid modifications that are consistent with the stored product semantic should be provided.
