【MSTN CE C++】如何给参考模型添加EC属性

Question

老师好，我现在想要在主模型里给参考模型添加EC属性，有没有什么方法，或者例子，能直接从主模型操作到参考模型的

如下是完整的代码，不管参考是不是当前dgn文件中的Model： 
 
	DgnAttachmentP dgnAtta = *ACTIVEMODEL->GetDgnAttachmentsP()->begin();
	if (dgnAtta->GetDgnModelP()->GetDgnFileP() == ISessionMgr::GetActiveDgnFile())
	{
 PersistentElementRefP perEleRef = dgnAtta->GetDgnModelP()->FindElementByID(1431);
 EditElementHandle eeh(perEleRef);
 ElementPropertiesSetterPtr propSet = ElementPropertiesSetter::Create();
 propSet->SetColor(3);
 propSet->Apply(eeh);
 eeh.ReplaceInModel(perEleRef);
	}
	else
	{
 DgnFileStatus dgnFileStatus; int defFileId = 0;
 DgnDocumentPtr dgnDoc = DgnDocument::CreateFromFileName(dgnFileStatus, dgnAtta->GetDgnModelP()->GetDgnFileP()->GetFileName().data(),
 NULL, defFileId, DgnDocument::FetchMode::Write);
 DgnFilePtr dgnFilePtr = DgnFile::Create(*dgnDoc, DgnFileOpenMode::ReadWrite);
 if (dgnFilePtr.IsNull())
 return;
 StatusInt openForWriteStatus;
 dgnFilePtr->LoadDgnFile(&openForWriteStatus);
 if (SUCCESS != openForWriteStatus)
 return;
 StatusInt status = dgnFilePtr->FillDictionaryModel();
 if (SUCCESS != status)
 {
 return;
 }
 ModelId mdoelId = dgnAtta->GetDgnModelP()->GetModelId();
 DgnModelPtr dgnModelPtr = dgnFilePtr->LoadModelById(mdoelId);
 dgnFilePtr->FillSectionsInModel(&*dgnModelPtr);

 EditElementHandle eeh(1431, &*dgnModelPtr);
 ElementRefP perEleRef = eeh.GetElementRef();
 ElementPropertiesSetterPtr propSet = ElementPropertiesSetter::Create();
 propSet->SetColor(3);
 propSet->Apply(eeh);
 eeh.ReplaceInModel(perEleRef);
 dgnFilePtr->ProcessChanges(DgnSaveReason::FileClose);
	}
