Abstract
State of the art automotive development processes are based on virtual product models, which include a digital representation of complete vehicle geometry and structures. Increasing computation performance and continuously growing demands on virtual development processes lead to the application of precise product representation within common CAD software packages. A specific challenge represents the creation of PVC-seams, which are used for corrosion protection of sheet metal components in automotive body in white design. Besides the high requirements of accurate geometric modeling in digital representation, modern development processes call for an increasing level of design automation. To fit both, the present approach introduces a method for an automatic generation of PVC-seams using the functionalities of commercial CAD software.
