Model simplification for meshing using face clustering

In this work a new method for CAD model simpliication is presented. The method is especially suited for simpliications performed in preparation for meshing the models. It uses a local analysis approach based on a clustering procedure. The method provides a generic approach for model simpliication. It is eecient and robust. It works on non-manifold models, free-form and linear faces, and models with large curved regions. It provides symmetric partitioning of details like blends and llets, resulting in more symmetric simpliied models.
