Aesthetic Feature-Based Parametric Shape Design and Evaluation of Products

A method of aesthetic feature-based parametric shape design for industrial sewing machines is presented using the shape control parameters to express aesthetic factors of the products.By revising the feature parameters of the model,differente styles of industrial sewing machines can be generated.Taking the feature parameters and the corresponding model’s aesthetic evaluation values as training samples,an evaluation system is built based on artificial neural network （ANN）.Finally the best sewing machine is determined by the evaluation system.
