CATIA二次开发入门教程---15 通过点击屏幕创建点
1 j. E( K, {1 n2 w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。

. @9 ?8 s/ e/ {3 f" a! A6 \) a& Q
void DialogTesTCmdDialog::OnPushButtonCreatePointPushBActivateNotification(CATCommand* cmd, CATNotification* evt, CATCommandClientData data)
& R; T. J" J: W- Q) Z5 ?- p{
  // Add your code here
      CreatePointCmd *createPoint = new CreatePointCmd();
! W: l2 K  z" u) A4 }! g" o. \( x; L3 q  H}
' ?" T' N6 x4 X7 W
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：

CATMathPlane plane = _Indication->GetMathPlane();
CATMathPoint point3D;

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