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。
0 h* ~5 ?! t: M2 ?6 q

void DialogTesTCmdDialog::OnPushButtonCreatePointPushBActivateNotification(CATCommand* cmd, CATNotification* evt, CATCommandClientData data)
{
9 U% t# T7 T; S  // Add your code here
      CreatePointCmd *createPoint = new CreatePointCmd();
1 e8 V( |& n; G}

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：

CATBoolean CreatePointCmd::ActionOne( void *data )
; G3 D. @- v3 G) D. e+ v{
  // TODO: Define the action associated with the transition
8 \& R+ X7 V8 q6 |  D  // ------------------------------------------------------
+ y8 u6 @6 z& _, L CATMathPoint2D point2D =  _Indication->GetValue();
# s4 I1 |4 z' V* N2 G2 |# H CATMathPlane plane = _Indication->GetMathPlane();
CATMathPoint point3D;
plane.EvalPoint(point2D.GetX(),point2D.GetY(),point3D);

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