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。


void DialogTesTCmdDialog::OnPushButtonCreatePointPushBActivateNotification(CATCommand* cmd, CATNotification* evt, CATCommandClientData data)
  G, }: ]) @& W  A% L; o9 j5 Q- n0 V{
; o: x- d# A" c2 V& |$ \  // Add your code here
' w% T; W9 w& l0 E$ \9 g) b      CreatePointCmd *createPoint = new CreatePointCmd();
}
2 J: J5 A/ e# E' i
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：
1 e1 M% a/ h) ]& S- p) Q& j  K0 p
CATBoolean CreatePointCmd::ActionOne( void *data )
2 c5 N5 J$ I1 q. x6 z! \{
  // TODO: Define the action associated with the transition
& }6 ]- o0 m* z8 _+ s! e9 z1 V  // ------------------------------------------------------
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;
