Nowadays the generation of CAD data out of existing models is a matter of high interest. Therefore 3D scanning systems are used to represent the models as a large set of digitised, unstructured point data. Surface reconstruction processes can then be used for automated generation of the desired 3D surface models. This paper describes the structuring of point data as a pre-processing before the actual surface reconstruction takes place. First, the focus is set to an algorithm to reduce the data of large point sets. Subsequent a method for curvature approximation, based on the Delaunay triangulation of a set of points, is described. By means of curvature discontinuities the points are grouped to represent separate surfaces of the model. With variational design processes the groups of points can be used to generate the final surfaces.
