Surface Quality

CAD surface quality results from the algorithmic properties of the CAD systems used, from the design history and from conversion processes via interfaces. CAD data with qualitative deficiencies often has to be imported and further processed in order to manufacture molds and dies. In addition to curvature, the most important evaluation criteria for CAD free-form surfaces include gaps and overlaps between the individual surfaces, polynomial degree and the number of surface segments as well as the layout of the surfaces in the overall topology. CAD surface quality can be improved in Tebis with little time and effort, which allows for better processing of the CAD data in design and manufacturing and its transfer to other CAD systems. This is realized with both automatic and manual optimization of the surfaces and results in quality up to class A.
