Abstract: To study the car body panels parameterized modeling method based on features, the concept of features was introduced in modeling for car body panels. The classifying method and control parameters of shape feature for car body panels were presented. The parameterized model for the mini car door internal panel of the QCJ7082 based on its features was constructed. It is obviously convenient to establish the parameterized model for car body panels by using parameterized modeling method based on features.
