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。

+ j: Z4 t1 b# u6 e) E% o
void DialogTesTCmdDialog::OnPushButtonCreatePointPushBActivateNotification(CATCommand* cmd, CATNotification* evt, CATCommandClientData data)
{
  // Add your code here
$ e$ r( {1 R& A- p      CreatePointCmd *createPoint = new CreatePointCmd();
}
, ?+ q, R, Y2 L/ O6 n$ X" x
0 R3 x2 C1 n+ I4 u* D7 D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：

. l1 \% n: \+ h3 j( Z5 p" f{

$ u5 E0 y8 @9 R: \8 P  // ------------------------------------------------------
CATMathPoint2D point2D =  _Indication->GetValue();
CATMathPlane plane = _Indication->GetMathPlane();
CATMathPoint point3D;
plane.EvalPoint(point2D.GetX(),point2D.GetY(),point3D);

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