CATIA二次开发入门教程---15 通过点击屏幕创建点
6 f  v/ ~& z. @# o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。

2 D# S  p; V1 u1 C
void DialogTesTCmdDialog::OnPushButtonCreatePointPushBActivateNotification(CATCommand* cmd, CATNotification* evt, CATCommandClientData data)
+ M# J1 B! k9 ~5 O% X{
2 T% T6 a1 C1 t7 p/ u5 y- Y  // Add your code here
+ p; R; F! R# C      CreatePointCmd *createPoint = new CreatePointCmd();
}
- @: H7 I0 U3 ^; T8 Y$ r
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 m- U7 G" O) Y1 v7 eCATBoolean CreatePointCmd::ActionOne( void *data )
{
  // TODO: Define the action associated with the transition
$ r% g) H0 B0 E- l: [+ S3 I  // ------------------------------------------------------
CATMathPoint2D point2D =  _Indication->GetValue();
CATMathPlane plane = _Indication->GetMathPlane();
2 E% O# a* B- X CATMathPoint point3D;
