Our self-developed models still in its infancy, research in this area is still relatively small. But with the rapid development of Chinas automobile industry, developed light quality, energy-efficient, environmentally friendly vehicles will become the future trend of development. Side panel is an important part of the car, its shape and assembly reliability have a significant impact on the overall shape. To combine ergonomic design, modeling, crafts to make cars more beautiful and practical. Side panels usually as surrounding parts of the base, especially the side wall outer panel, side wall outer panel in a leadership position in the design, which directly affects the open door, and the whole body welding relations and order. And regardless of the side panels is still in the design stage of product design in mold design and manufacturing stage, the share of development and design cycle is the longest direct impact determines the progress of the entire project. So early in the design stage, the assembly of components associated with it disposed of on the obvious is particularly importan
