The invention notably relates to a computer-implemented method for designing, with a CAD system, a 3D modeled object representing a mechanical part. The method comprises providing a B-rep representingthe mechanical part. The B-Rep has faces and edges. The method further comprises providing a first set of faces and a feature type. The feature type is either a depression feature type or a protrusion feature type. The method further comprises, automatically by the CAD system, recognizing a second set of faces within the first set of faces. The second set of faces represents a feature of the provided feature type. This constitutes an improved method for designing a mechanical part. 本发明特别涉及一种用于利用CAD系统来设计表示机械部件的3D建模对象的计算机实施的方法。所述方法包括提供表示所述机械部件的边界表示。所述边界表示具有面和边。所述方法还包括提供面的第一集合和特征类型。所述特征类型是凹陷特征类型或凸起特征类型。所述方法还包括由所述CAD系统自动识别面的所述第一集合内的面的第二集合。面的所述第二集合表示所提供的特征类型的特征。其构成了用于设计机械部件的改进的方法。
