Abstract
To a large extent, the success of the product shape design depends on whether the geometric modeling systems can satisfy more and more complicated design demands in the engineering field. This paper proposes a shape design method based on semantic features for complex CAD surface. By the proposed method, we can easily meet the complicated design requirements, since the semantic can effectively represent the design intent. We discussed three aspects in shape design using semantic features, which are semantic design demands of the target surface, geometric constraints in accordance with semantic features, and surface shape deformation under the geometric constraints, respectively. The basic semantic features of geometric models drive the deformation of the target surface shape by changing the related constraint, and the desirable features are added to the CAD surface shape. The examples of the car shape design are presented to verify the effectives of our method.
