- The empirical formula of human body feature points counted by the US SAE is used for reference. It is loaded on ACAD after compiled. The enveloping curve of human body feature points can be drawn according to automobile general layout. 借鉴美国SAE统计的人体特征点的经验公式,用ADS语言编写程序,经编译后生成EXP(保护模式的可执行文件)文件,加载到ACAD上,根据输入的汽车总体布置参数,在ACAD环境中绘制出人体特征点的包络线,这些曲线完全可以代替过去图形样板的功能,利用这些曲线可以直接在ACAD环境中进行汽车车身设计,也可对在ACAD环境中设计好的汽车驾驶室进行校核。
