CATIA二次开发入门教程---15 通过点击屏幕创建点
! T1 o# t3 l. R# [/ ?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。

1 o9 ]3 b* A4 o; S. F! [
void DialogTesTCmdDialog::OnPushButtonCreatePointPushBActivateNotification(CATCommand* cmd, CATNotification* evt, CATCommandClientData data)
{
: u8 R4 ]! m! a$ W! l& F/ d  // Add your code here
4 n3 _! a, o9 N3 ~! R$ s/ G; L      CreatePointCmd *createPoint = new CreatePointCmd();
7 z" N4 s8 {) P$ c}

2 h- T4 @2 N. H9 n. b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：

{

  // ------------------------------------------------------
CATMathPoint2D point2D =  _Indication->GetValue();
CATMathPlane plane = _Indication->GetMathPlane();
CATMathPoint point3D;
plane.EvalPoint(point2D.GetX(),point2D.GetY(),point3D);

$ \9 q5 x" g2 t* B' n& b cout<<"Point coordinates:" << point3D.GetX() << "," << point3D.GetY() << "," << point3D.GetZ()<<endl;
