The simplicity of product modeling geometry is retained, and the most comfortable curvature modeling is optimized through the relationship between different size chamfers and chamfer curvature. The three-dimensional composition theory is used to cut and evolve the geometric shape, so that the product has a sense of hierarchy on the basis of retaining the simplicity of the product shape. Retaining the same chamfer size and curvature as the product is a unified feature of the product. Breaking the inherent basic shape with trapezoidal segmentation on the modeling inspiration gives people a sense of freshness. Can be customized according to consumer demand laser nameplate, so that the product can give consumers unique
