CAD model simplification using feature simplifications

Abstract

We propose an enhanced method for feature-based simplification of feature-based CAD models. In previous feature-based simplification methods, a CAD model is progressively simplified by suppressing individual features with low importance one at a time, whereas in the proposed method, each feature itself is progressively simplified based on its feature type. The proposed method provides a user with a further subdivided level of simplification. In the proposed method, features are categorized into sketch-based features and non-sketch-based features. The sketch-based features are simplified using three sketch simplification operations. The non-sketch-based features are simplified by converting them into simpler features, or changing their parameters. To demonstrate the proposed method, we present the implementation and experiment results.
