title Geometric reasoning for the extraction of form features

summary The primary limitation of feature-recognition approaches, namely their lack of generalization, has been addressed by the development of feature-extraction techniques. This paper presents a boundary-based procedurefor the sequential extraction of form features from CAD models of objects with planar surfaces. An object is viewed as an initial basic shape that has been iteratively altered through the introduction of form features.Form features are first classified based on their effect in changing a basic shape. Geometric reasoning is then used to obtain generalized properties of the form-features' classes. Finally, form-features' classes aresequentially extracted based on the obtained properties.
