A feature in computer-aided design (CAD) software is a region of a part with some interesting geometric or topological patterns. The feature information has a greater significance because it helps the process planner to determine the machining tools and manufacturing processes required to machine the designed objects. A feature library contains simple, intersecting, and compound features. Features are also classified as prismatic and rotational features. Prismatic features are further categorized into depression and boss features. The depression features are further subdivided into two categories, that is, flat and cylindrical. The flat features are step, slot, and pocket features that can be through, blind, and round corners. The cylindrical features are hole, counterbore, and countersink features. Feature recognition involves the identification and grouping of feature entities from a geometric model. Such "post definition" of features can be done interactively or automatically. Automatic feature recognition has fundamental significance from the integration perspective of product development cycle.
