NX二次开发：保存时导出PDF并打开

该工程为在保存时执行开发的功能，函数入口点ufput。其他还有新建、打开、另存等都可以加入开发的操作，具体看UF_EXIT下的介绍。

用户出口是一个可选特性，允许你在NX中某些预定义的位置(或出口)自动运行Open C API程序。如果你进入其中一个出口，NX会检查你是否定义了指向Open C API程序位置的指针。如果定义了指针，NX将运行Open C API程序。指针是一个环境变量。

注意：

一定要设置环境变量指向自己生成的DLL。例如：USER_FILE=E:workspaceInforetcnx_projectapplicationtcnx_project.dll
