主要实现在proe模型中如何实现参数化建模的详细例子，对proe关于CAD部分的二次开发很有帮助-Mainly implemented in proe model example of how to implement a detailed parametric modeling proe secondary development of CAD part about helpful

Pro/E是使用非常广泛的三维参数化建模软件，其中很多曲线是很难画出的，而用本程序的方程可以非常方便的画出。-Pro/E is to use a very wide range of three-dimensional parametric modeling software, which is very difficult to draw a lot of curves, and the use of this procedure can be very convenient equation
