CATIA二次开发入门教程---15 通过点击屏幕创建点
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。

$ h6 P/ k; Z0 W8 c
void DialogTesTCmdDialog::OnPushButtonCreatePointPushBActivateNotification(CATCommand* cmd, CATNotification* evt, CATCommandClientData data)
+ P: y+ d' }) N7 V4 J7 u6 {' |{

      CreatePointCmd *createPoint = new CreatePointCmd();
}

: w) h3 t- f: [8 ^% x5 e! |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：

( L& p7 p$ N+ x  ], O, VCATBoolean CreatePointCmd::ActionOne( void *data )

  // TODO: Define the action associated with the transition

CATMathPlane plane = _Indication->GetMathPlane();
CATMathPoint point3D;
plane.EvalPoint(point2D.GetX(),point2D.GetY(),point3D);

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