CATIA二次开发入门教程---15 通过点击屏幕创建点
( z  S/ O8 P5 b- t8 u. g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。

5 }& ?/ Z, N/ Z+ A; f
void DialogTesTCmdDialog::OnPushButtonCreatePointPushBActivateNotification(CATCommand* cmd, CATNotification* evt, CATCommandClientData data)
{

! M) i4 }; n0 M: t- i      CreatePointCmd *createPoint = new CreatePointCmd();
5 a( E" r7 E5 l$ ?0 e}

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 S; L8 l- d# O- ~2 O+ ZCATBoolean CreatePointCmd::ActionOne( void *data )
{
- w0 b! S4 c( O7 S( J1 o, N  // TODO: Define the action associated with the transition
