Free-form curves and surfaces are very important for sophisticated CAD/CAM Systems. Apart from the geometric modelling aspect of these curves and surfaces, the analysis of their quality is a necessary tool in the design and construction process. The purpose of this paper is to give a critical survey on curve and surface interrogation methods and to present generalized focal surfaces as a new surface interrogation tool.
