CATIA二次开发入门教程---15 通过点击屏幕创建点
% w% Y3 u+ T7 n通过点击屏幕，自动创建点， 这里直接建立了一个简单的对话框，通过pushbutton来添加一个回掉函数，函数里面去执行创建点的类。

' K+ K! f$ r9 X{
  // Add your code here
      CreatePointCmd *createPoint = new CreatePointCmd();

新建一个catia 的命令，名称为 CreatePointCmd ，接下来要做的就是在 action one 里面进行点的创建，代码如下：
& ?+ @8 b& Y- W1 c, }- u: u2 w
CATBoolean CreatePointCmd::ActionOne( void *data )

  _Indication指的是什么呀
