1、汽车行业玻璃升降器百线图的建立教程百格线汽车行业CATIA百线图的构造汽车中百位线的作用是能够快速得知汽车各部分零件相对于汽车坐标系的位置（如图所示）。在车身质量控制，人机工程等方面相当重要。这一用途同样适用于模具及其它行业，比如汽车玻璃升降器中百线图的设计（如图所示）。对于这样的百位线图用AUTOCAD软件进行设计的工程师一般都通过一步一步画直线，阵列，画圆来实现。当然用CATIA软件进行三维模型设计，然后投影成工程图，也可以用如上的方法一步一步画出百位线，但这样工作效率非常低。因此网上很多朋友就询问有没有比较好的方法自动生成百位线。那么我在这介绍两种种CATIA软件自动生成百位线的方法，这

2、两种方法在CATIA V5 R16以上的环境下测试过都没有问题。首先在装配体里面新建零件，在为新零件建立新原点时选择否，新建的三个坐标平面就是整个汽车的坐标平面，这样整个车的坐标系就出来了，如下图所示进入CATIA工程制图界面，新建空白文件进入工程图纸页面，然后投影主视图，但要注意工程图纸选择投影品面时要选择新建零件的坐标平面，也就是坐标原点所在的平面（这个很重要）。投影完成后在投影图的左下角和右上角分别建立两点，着两点的位置所做的矩形能够将整个图纸包含即可，然后选择工具宏（或Alt+F8）点击宏库目录添加现有库找到宏所在的文件夹，然后选择宏点击运行，如下图所示确定百线格为100，如下图所示确

3、定后点击左下角的点，再确定后点击右上角的点，完成后白线图就生成了，如下图所示：Catia百格线生成宏你是否为在Catia做2D图纸的时候，画百格线而伤脑筋呢？别担心，接下来我告诉你一个简单的方法1.新建一个txt文本文档，比如Draw-Grid.txt2.把以下内容复制到Draw-Grid.txt中这里开始，不要复制我Option Explicit * Purpose: This macro allows you to create Grid line in CATIA drawing Author: chenqa Languages: VBScript Locales: English De
