Creo二次开发：坐标系自动装配

 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);
    ProPath path=L"udf_def_csys.gph";
    err=ProUdfdataPathSet(data,path);
    ProSelection ref_item_csy;
    ProModelitem mdl_itm_top;
    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);

    err=ProUdfdataScaleSet(data,PROUDFSCALETYPE_USER,2.0);
    err=ProUdfdataDimdisplaySet(data,PROUDFDIMDISP_NORMAL);
    err=ProUdfdataDependencySet(data,PROUDFDEPENDENCY_INDEPENDENT);

    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)
{    
    ProErr  err;

}
void CPart3DDlg::OnBnClickedBtnTabAdd()

    err=ProSelect("prt_or_asm",1,NULL,NULL,NULL,NULL,&sels,&n_sels);
    if (err!=PRO_TK_NO_ERROR)
    {
        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);

运行结果
