在瓶底可以点选放置一个时间标签（标签可以是零件）

代码如下：

//创建坐标系UDF
void putcsys(ProMdl mdl,double x,double y,double z)
{
   ProError err=PRO_TK_NO_ERROR;
   ProUdfdata data;
   err=ProUdfdataAlloc(&data);

   err=ProModelitemByNameInit(mdl,PRO_CSYS,_T("ASM_DEF_CSYS"),&mdl_itm_top);
   err=ProSelectionAlloc(NULL,&mdl_itm_top,&ref_item_csy);
   ProUdfreference reference_csy;
   err=ProUdfreferenceAlloc(_T("csys"),ref_item_csy,PRO_B_FALSE,&reference_csy);
   err=ProUdfdataReferenceAdd(data,reference_csy);

   ProUdfvardim vardim_x;
   err=ProUdfvardimAlloc(_T("d9"),x,PROUDFVARTYPE_DIM,&vardim_x);
   err=ProUdfdataUdfvardimAdd(data,vardim_x);

   ProUdfvardim vardim_y;
   err=ProUdfvardimAlloc(_T("d10"),y,PROUDFVARTYPE_DIM,&vardim_y);
   err=ProUdfdataUdfvardimAdd(data,vardim_y);

   ProUdfvardim vardim_z;
   err=ProUdfvardimAlloc(_T("d11"),z,PROUDFVARTYPE_DIM,&vardim_z);
   err=ProUdfdataUdfvardimAdd(data,vardim_z);

   ProUdfCreateOption op={PROUDFOPT_FIX_MODEL_UI_OFF};
   ProGroup udf;
   err=ProUdfCreate((ProSolid)mdl,data,NULL,&op,1,&udf);
   if(err!=PRO_TK_NO_ERROR)
   {
       AfxMessageBox(_T("Udf创建失败"));
   }
   ProUdfdataFree(data);
   ProUdfvardimFree(vardim_x);
   ProUdfvardimFree(vardim_y);
   ProUdfvardimFree(vardim_z);

   ProUdfreferenceFree(reference_csy);
   ProSelectionFree(&ref_item_csy);

   int wid=0;
   err=ProWindowCurrentGet(&wid);
   err=ProWindowRefresh(wid);
}
//通过坐标系自动装配
ProError UserAssembleByCsys(ProAssembly asm_mdl,ProSolid comp_mdl)

    { 0.0, 0.0, 0.0, 1.0}};

   //保存添加入组件中的元件

       return;
   }
   ProSelectionPoint3dGet(sels[0],position);
   //放置坐标系udf
   putcsys((ProSolid)asm_mdl,position[0],position[1],position[2]);
   //读出要添加的零件模型
   ProMdlRetrieve(L"comp.prt",PRO_MDL_PART,&comp_mdl);
   //自动装配
   UserAssembleByCsys((ProAssembly)asm_mdl,(ProSolid)comp_mdl);

   ProWindowActivate(pid);
}

运行结果
