基于ALIAS软件的汽车曲面评价方式

Evaluation Method of Automobile Surface Based on ALIAS Software

数字模型上曲面是由点、线组成,点的排布好坏影响到线的走势,而线的走势直接影响曲面的特征、质量,因此对点的排布、线的走势、曲线和曲面的连续性要求做了表述,另外对钣金、塑料件等相互关联的翻边和圆角大小也进行了定义。

The surface on the digital model is composed of points and lines. The layout of points affects the trend of lines, while the trend of lines directly affects the characteristics and quality of surfaces. Therefore, the layout of points, the trend of lines, the continuity requirements of curves and surfaces are described. In addition, the size of flanging and fillets associated with sheet metal and plastic parts are defined.
