Beauti cation aims to improve such models in a post-processing step solely working with the boundary representation model. The improved model should exhibit topological and geometric regularities representing the original, ideal design intent. This paper gives an overview of algorithms for a complete beauti cation system suitable for improving the topology and the geometry of low to medium complexity reverse engineered models.J.6 [ComputerAided Engineering]ComputerAided Design10.2312/sm.20041398255-260
