In car body design there exist various possibilities to design surfaces with given boundaries. In many cases the resulting surfaces are not automatically smooth enough. A method is presented to define reflection lines on special splines as, for example, the intersection curves of a surface and a family of planes. These reflection lines represent surface irregularities in a very sensitive manner. If the reflection lines have to be changed, a suitable new family of splines is calculated. These smoothed splines can be used to create a smoothed surface. The resulting algorithm has been implemented in a CADCAM system.
