This thesis work has been performed at Benteler Engineering Service in Gothenburg in cooperation with Benteler Aluminium System Norway AS in Raufoss. Since the requirements on a product are changed several times during a product development process in the automotive industry, the desire to develop parts faster has increased. Components with complex geometries can take a large amount of time to design and when requirements on the design are changed the CAD-model has to be remade. A model with a complex geometry, which often is exposed to changes, is the B-pillar in the car. To achieve a more time efficient process for the B-pillar, an investigation was made to see if parameterization of the CAD-model could be made to save time in the development process. The result of this has shown that if the model is supposed to be changed more than three times parameterization is something that should be considered.

Different strategies for parameterization that could support the development process of the CAD-model of a B-pillar have been compared to investigate which strategy that was best suited for this project.

The goal to create a CAD-model of a generic B-pillar as a showpiece where parameters control the geometry and where changes of the main dimensions can be implemented faster than in a model without parameterization, has been fulfilled.
