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)
{
0 i1 s+ o, j9 W/ ]$ ], s+ n  // Add your code here
# c3 {; b: q) O      CreatePointCmd *createPoint = new CreatePointCmd();
0 l+ }/ D5 V7 t8 U: W4 J. W( R0 x0 P% Z}

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：

4 F/ @( c4 j. L1 N% {8 M$ eCATBoolean CreatePointCmd::ActionOne( void *data )
/ A* [% a7 K+ [5 ^& F/ V{
  // TODO: Define the action associated with the transition
  // ------------------------------------------------------
CATMathPoint2D point2D =  _Indication->GetValue();
2 R% C1 [" s- [; P" b CATMathPlane plane = _Indication->GetMathPlane();
CATMathPoint point3D;
plane.EvalPoint(point2D.GetX(),point2D.GetY(),point3D);
