UFUN的API里是没有切换到工程图的函数的，NXOPEN里是有方法可以用的。不过应该是不支持NX9以下的版本。
NX9的不能录制出来，在UI类里有方法
NX9+VS2012 #include <uf.h>
#include <NXOpen/UI.hxx>
#include <NXOpen/MenuBar_MenuBarManager.hxx> NXOpen::UI *theUI = NXOpen::UI::GetUI(); UF_initialize(); //NX9只有切换到工程图模块的方法，没有获取当前模块名字的方法，所以使用UFUN的函数，混合开发。
int ModuleId;
UF_ask_application_module(&ModuleId);//获取当前所在的模块 if (ModuleId != )//此处等于1，是从帮助找到的，在帮助搜DRAFTING，就可以搜到一堆的宏定义，UG_APP_DRAFTING就等于1.
{
theUI->MenuBarManager()->ApplicationSwitchRequest("UG_APP_DRAFTING");//切换到工程图模块
} UF_terminate();
NX11的可以录制出来，在Session类里有方法。(从NX10开始就可以录制出来了)
NX11+VS2013 #include <NXOpen/Session.hxx> NXOpen::Session *theSession = NXOpen::Session::GetSession();
NXOpen::Part *workPart(theSession->Parts()->Work());
NXOpen::Part *displayPart(theSession->Parts()->Display()); theSession->ApplicationSwitchImmediate("UG_APP_DRAFTING");//切换到工程图模块 NXString Name= theSession->ApplicationName();//获取当前模块的名字 uc1601(Name.GetLocaleText(), );//打印
