CATIA二次开发入门教程---15 通过点击屏幕创建点
# N4 o5 p: d6 i- _& d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。


, h! Y' F- H, n0 U) D! Fvoid DialogTesTCmdDialog::OnPushButtonCreatePointPushBActivateNotification(CATCommand* cmd, CATNotification* evt, CATCommandClientData data)
{
: P6 j; s5 }  A+ K3 s  // Add your code here
$ b. _, j, @$ _0 b' Z. |! \      CreatePointCmd *createPoint = new CreatePointCmd();
}
% N$ U* y2 w' C0 M4 [' j
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：

* ~# m" k2 ]- n1 Y; `* W/ fCATBoolean CreatePointCmd::ActionOne( void *data )
{
2 R  e( F) Y  J, [! }  // TODO: Define the action associated with the transition
4 E# H) s  X. N$ d9 q% |4 d  // ------------------------------------------------------
CATMathPoint2D point2D =  _Indication->GetValue();
CATMathPlane plane = _Indication->GetMathPlane();
7 Y+ _3 ^% ^+ p CATMathPoint point3D;
* w, ^- \3 ]3 y plane.EvalPoint(point2D.GetX(),point2D.GetY(),point3D);

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