| Sumario: | Feature-based design is becoming one of the basic design paradigms of CAD systems. In this paradigm the basic unit is a feature and parts are constructed from a sequence of feature attachment operations. The type and number of possible features involved depend upon product type, the application reasoning process and the level of abstraction. Therefore to provide CAD systems with a basic mechanism to define features that fit the end-user needs seems more appropiate than trying to provide a large repertoire of features covering every possible application. A procedural mechanism to generate and use user-defined features in a feature-based design paradigm is proposed. The usefulness of the mechanism relies on two functional capabilities. First the shape and size of the user defined features are instantiated according to parameter values given by the end-user. Second the end-user positions and orients the feature in the part being designed by means of geometric gestures on geometric references. |
