Abstract
Whenever products are manufactured there are deviations from the ideal geometry defined in the CAD-system. In this report a prototype is presented which allows a user to set up non-ideal visualizations of slightly deformed parts easily and quickly. The method can be used in the early stages of product development to ensure that aesthetic quality is taken into account before a real product has been manufactured. Very important key criteria for the appearance of several products, e.g. automotive car bodies or consumer products are gap and flush measurements. Therefore the developed method allows an intuitive and fast way to generate visualizations which can be used in design reviews. By using efficient data structures for the calculation of the deformation it is possible to change the shape of objects interactively during the design review itself. A case study has been performed to show that it’s possible to generate simulations which are close to the output of manufacturing simulations.
