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。


3 Q8 X: C5 r# b! O( I, N- I  S2 a$ Zvoid DialogTesTCmdDialog::OnPushButtonCreatePointPushBActivateNotification(CATCommand* cmd, CATNotification* evt, CATCommandClientData data)

9 Q% [; V5 o0 e$ W. S$ |# q! \}
; w: F* B4 Y/ Y
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% _- C3 C& v3 x
: G& ?% g+ ^5 `9 d6 X' _# v  eCATBoolean CreatePointCmd::ActionOne( void *data )
! \" Z% `- D3 G  L  m  S+ h& ~{

  // ------------------------------------------------------
CATMathPoint2D point2D =  _Indication->GetValue();
9 H6 }1 w! U7 c& O CATMathPlane plane = _Indication->GetMathPlane();
CATMathPoint point3D;
plane.EvalPoint(point2D.GetX(),point2D.GetY(),point3D);

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