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。

! r/ R! s; [6 H
void DialogTesTCmdDialog::OnPushButtonCreatePointPushBActivateNotification(CATCommand* cmd, CATNotification* evt, CATCommandClientData data)
{
  // Add your code here
; h: h( }: o% {- n5 |5 M; a. N" z      CreatePointCmd *createPoint = new CreatePointCmd();
}
- }$ K8 o! J( a8 F- {3 A- u. u
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：
. U! N' j5 f  k7 C, n' }
2 u" M- [+ \$ V! gCATBoolean CreatePointCmd::ActionOne( void *data )
{
