Traditional clay models are almost all made by hand. During the production process, it is difficult to ensure that the actual model and the design drawings and 3D shapes can be well matched, and sometimes there are even large differences, especially for large models like cars. Object models often have left-right asymmetry in the model's exterior surface. In order to ensure the symmetry of the sludge models such as automobiles, the current common practice is: use the criss-cross scales on the platform of the automobile sludge model as a reference, and use measuring tools such as height gauges and calipers to first trace points on one side of the sludge to find out these The coordinates of the points are reflected to the other side by measuring tools such as height gauges and calipers, and the modeler's observation is used to determine whether the model is symmetrical, so as to further correct and make it. Since the above method of drawing points mainly relies on the subjective experience of the operator to judge the shape, size and symmetry of the model, the accuracy of the model produced is not high and cannot meet the design requirements; at the same time, the process of drawing points is cumbersome, and the labor intensity Big and not very efficient. A small number of automobile design companies use 3D liner to process automobile clay models, but the structure of 3D liner is complicated and expensive, and it cannot be popularized on a large scale.
