MSCE SDK中取消了原来V8i下的文字操作来C函数mdlText_xxx，您需要重新学习类TextBlock，它能同时表达文字元素（TextElement）和文字节点元素（TextNodeElement）。

如下代码是一个典型的通过TextBlock创建一个MSCE下的文字的实例：

/*--------------------------------------------------------
| createText
+-------------------------------------------------------*/
TextFieldPtr createField(DgnModelR model)
    {
    // "DgnElementSchema" and "ArcElement" are found from ...\MicroStation\ECSchemas\Dgn\DgnElementSchema.01.00.ecschema.xml
    DgnFileP   pDgnFile = ISessionMgr::GetActiveDgnFile();
    //SchemaInfo schemaInfo(ECN::SchemaKey(L"DgnElementSchema", 1, 0), *pDgnFile);
	SchemaInfo schemaInfo(ECN::SchemaKey(L"DgnCustomItemTypes_Architectural", 1, 0), *pDgnFile);
	DgnECManagerR ecMan = DgnECManager::GetManager();
	ECN::ECSchemaPtr pSchema = ecMan.LocateSchemaInDgnFile(schemaInfo, ECN::SchemaMatchType::SCHEMAMATCHTYPE_LatestCompatible);
    if (pSchema == NULL)
	{
		mdlDialog_dmsgsPrint(L"Can't find identified schema");
		return NULL;
	}
    //ECN::ECClassCR   ecClass = *pSchema->GetClassCP(L"ArcElement");
	//ECN::ECClassCR   ecClass = *pSchema->GetClassCP(L"LineElement");
	ECN::ECClassCR   ecClass = *pSchema->GetClassCP(L"Doors");
    
	ElementId  elemId = 49064L;  // An arc element id
    ElementHandle elem(elemId, &model);
    if (!elem.IsValid())
        return NULL;
    DgnElementECInstancePtr pElemInst = ecMan.FindInstanceOnElement(elem, ecClass);

	//return TextField::CreateForElement(*pElemInst, L"Length", nullptr, model);
    //return TextField::CreateForElement(*pElemInst, L"TotalLength", nullptr, model);
	return TextField::CreateForElement(*pElemInst, L"Type", nullptr, model);
    }

void createText(WCharCP  unparsed)
    {
    DgnModelP       pActiveModel = ISessionMgr::GetActiveDgnModelP();
    TextBlockPropertiesPtr  pTBProp = TextBlockProperties::Create(*pActiveModel);
    pTBProp->SetIsViewIndependent(true);
    ParagraphPropertiesPtr  pParaProp = ParagraphProperties::Create(*pActiveModel);
    //DgnTextStylePtr         pTextStyle = DgnTextStyle::GetActive();
	DgnTextStylePtr         pTextStyle = DgnTextStyle::GetByName(L"5mm", StyleIteratorMode::ActiveFileAndLibraries);
    RunPropertiesPtr        pRunProp = RunProperties::Create(*pTextStyle, *pActiveModel);
	//DPoint2d fontSize = DPoint2d::From(2000, 1000);
	//pRunProp->SetFontSize(fontSize);
    TextBlockPtr pTextBlock = TextBlock::Create(*pTBProp, *pParaProp, *pRunProp, *pActiveModel);
    pTextBlock->AppendText(L"This is a ViewIndependent text");

    //TextFieldPtr pField = createField(*pActiveModel);
    //if (pField != NULL)
    //    pTextBlock->AppendField(*pField);

	//pTextBlock->AppendParagraphBreak();
	//pTextBlock->AppendText(L"Second Line");

    EditElementHandle  eeh;
    if (TEXTBLOCK_TO_ELEMENT_RESULT_Success ==
        TextHandlerBase::CreateElement(eeh, nullptr, *pTextBlock))
        {
		ElementPropertiesSetterPtr setter = ElementPropertiesSetter::Create();
		setter->SetColor(3); // 3 -- Red
		setter->Apply(eeh);

        eeh.AddToModel();
        }
    }

其中注释掉的一些行也都具有特定含义，取消注释能使程序功能更强大，比如，创建带有文字域（TextField）的文字、多行文字等。
