Abstract:
A computerized method of representing a feature of a parametric solid model comprising:obtaining information relating to a feature of a parametric modeled solid body;storing the information in object instances represented in a hierarchical framework wherein the hierarchical framework comprises:(a) an abstract descriptor class for a feature, wherein an instance of an implemented descriptor classes provides geometric information of a feature; and(b) an informer class for a feature, wherein the informer class provides information about the feature that relates the feature to external parameters, wherein the informer class is selected from a group comprising:(i) an abstract feature locator class that provides location information regarding where to place a feature on a drawing;(ii) an abstract feature terminator class that provides termination characteristics of a feature; and(iii) an abstract feature combiner class that provides how to combine a feature with a second feature of the parametrically modeled solid body.
