Abstract: Editing features of a history-based computer-aided design (CAD) model may be difficult and may require redesigning much of the CAD model modify features. The solutions described herein allow a design engineer to modify an existing history-based CAD model by automatically determining history-based features that need to be converted to direct-edit features, creating a body of direct-edit features from the determined features, and creating a model containing both the direct-edit feature body and remaining history-based features. Such a CAD model containing both kinds of features may be referred to as a hybrid model.
