CATIA二次开发入门教程---15 通过点击屏幕创建点
# }' l0 ?  a9 C8 I* i' X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。

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：

CATBoolean CreatePointCmd::ActionOne( void *data )
* v$ a2 R+ H( @9 w! C{

CATMathPoint2D point2D =  _Indication->GetValue();
CATMathPlane plane = _Indication->GetMathPlane();
* w1 _; y; ]; N  k: J CATMathPoint point3D;
plane.EvalPoint(point2D.GetX(),point2D.GetY(),point3D);

cout<<"Point coordinates:" << point3D.GetX() << "," << point3D.GetY() << "," << point3D.GetZ()<<endl;

  _Indication指的是什么呀
