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。

  ?  o7 n; f" K3 G6 i0 V
0 m( O9 t, W4 i# @void DialogTesTCmdDialog::OnPushButtonCreatePointPushBActivateNotification(CATCommand* cmd, CATNotification* evt, CATCommandClientData data)
{
  // Add your code here
; h! @/ E7 ?2 k$ E" d3 _8 j      CreatePointCmd *createPoint = new CreatePointCmd();
# q$ e5 O- e& f( m}

9 d2 P( D0 m) k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：
