* S8 c7 w" N8 D- t6 L. s, w8 a1 V      企业进行产品设计的时候,往往需要使用三维CAD软件进行建模,来构建产品的造型,再进行一些细节的调整、打磨。因此,CAD软件的建模效果,对产品的造型有着重要的影响。从设计角度出发,优质产品的美观度,实用度都对设计有较高要求,而从产品生产的角度来看,优质的产品,在生产过程中能最大化地利用上所有的材料。
- n6 k! ]% S1 n& q: x      当前,市面上各种三维CAD设计软件,在建模方面都有自己的特点,而常见的,主要有曲线建模、实体建模、混合建模这三种。其中,混合建模相对曲面建模和实体建模来说,是一个较新的概念。尽管每个软件对混合建模都有不同的解释,但笔者相信很多使用三维CAD设计软件的工程师,对这个概念还是比较清晰的。下面我们通过简单的对比,还有一些图例,来说明下混合建模跟另外两种传统的建模方式之间的区别。8 q  ]. m1 n0 T6 T: v1 Y5 I

% s6 i1 U" [5 X# q      从上图可以看出,工程师在做产品设计的时候,要么先做线框,然后再设计面,这样一步步来完成整个产品的设计;或者选择直接通过实体的加减运算,来完成产品的设计。然而,现在消费者对产品外型的要求越来越高,企业为了占领市场,也会越来越注重产品的外型设计效果,而仅通过传统的设计方法,已经无法很好地去满足设计需求了。因此,混合建模的出现,则能让设计工程师在设计过程中获得更多设计的灵活体验,也补足了单纯的曲线建模或者实体建模的不足,从而设计出更好的产品。; i, s. T7 c" q) o, d

      【常规设计】:一般要通过“面”功能来做出车牌的安装位(如下图),然后使用“面修剪”或者“合并”等功能,把车牌和后保险杠这两个面组合在一起。这种方法操作步骤繁多,且实际操作起来,效果也不够直观,影响设计工程师的工作效率。
