In this work a new method for CAD model simplification is presented. The method is especially suited for simplifications 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 simplification. It is efficient 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 fillets, resulting in more symmetric simplified models.
