【MSCE c#】tekla建立的模型导出成ifc格式后，ms查看属性相关问题

Question

如下图红色框内所示，我是用ms up17 打开，是可以看到的。但是用ms up15打开 这些红色框体里的属性都看不到。 
 并且用获取ec属性也获取不到。我想通过二次开发获取这个属性，应该怎么做？

这些属性获取起来还是比较麻烦的，如下c/c++示例代码演示了获取&ldquo;格栅板&rdquo;的属性： 
 ElementAgenda selectset;
	SelectionSetManager::GetManager().BuildAgenda(selectset);
	if (selectset.GetCount() < 1)
	{
 return;
	}
	EditElementHandle& eeh = selectset[0]; 
	DgnFileP dgnFile = ISessionMgr::GetActiveDgnFile();
	SchemaInfo schemaInfo(ECN::SchemaKey(L"IFC2x3", 1, 0), *dgnFile);
	DgnECManagerR ecMan = DgnECManager::GetManager();
	ECN::ECSchemaPtr pSchema = ecMan.LocateSchemaInDgnFile(schemaInfo, ECN::SchemaMatchType::SCHEMAMATCHTYPE_LatestCompatible);
	if (pSchema.IsNull())
	{
 mdlDialog_dmsgsPrint(L"Can't find BaseElementSchema schema");
 return;
	}
	ECN::ECRelationshipClassP pRelaClass = pSchema->GetClassP(L"IfcRelDefinesProperties_RelatedObjects")->GetRelationshipClassP();
	ECN::ECRelationshipClassP pRRelaClass = pSchema->GetClassP(L"IfcRelDefinesByPropertiesProperties_RelatingPropertyDefinition")->GetRelationshipClassP();
	ECN::ECClassP pVolClass = pSchema->GetClassP(L"IfcPlate");
	DgnElementECInstancePtr pInstance = ecMan.FindInstanceOnElement(eeh, *pVolClass, true); //polymorphic=true is important
	if (pInstance.IsNull())
	{
 mdlDialog_dmsgsPrint(L"pInstance is null");
 return;
	} 
	QueryRelatedClassSpecifierPtr qrcs = QueryRelatedClassSpecifier::Create(*pRelaClass,NULL, ECN::STRENGTHDIRECTION_Backward);
	DgnECInstanceCreateOptions options = DgnECInstanceCreateOptions();
	DgnECInstanceCreateContext insCreateCon(options);
	DgnECInstanceIterable dgnECInsIter= DgnECManager::GetManager().FindRelatedInstances(*pInstance, *qrcs, insCreateCon); 
	for (DgnECInstanceIterable::const_iterator iter = dgnECInsIter.begin(); iter != dgnECInsIter.end(); ++iter)
	{
 DgnECInstancePtr instance = *iter;
 QueryRelatedClassSpecifierPtr qrcsCur = QueryRelatedClassSpecifier::Create(*pRRelaClass);
 DgnECInstanceIterable dgnECInsIterCur = DgnECManager::GetManager().FindRelatedInstances(*instance, *qrcsCur, insCreateCon);
 for (DgnECInstanceIterable::const_iterator iterCur = dgnECInsIterCur.begin(); iterCur != dgnECInsIterCur.end(); ++iterCur)
 {
 DgnECInstancePtr instanceCur = *iterCur; 
 WPrintfString wStrCur(L"Class__%s", instanceCur->GetClass().GetFullName());
 mdlDialog_dmsgsPrint(wStrCur);
 ECPropertyIterable ecPropIter = instanceCur->GetClass().GetProperties();
 for (ECPropertyIterable::const_iterator iterCCur = ecPropIter.begin(); iterCCur != ecPropIter.end(); ++iterCCur)
 {
 ECValue curECValue;
 instanceCur->GetValue(curECValue, (*iterCCur)->GetName().GetWCharCP());
 WPrintfString wStr(L"Property__%s	Value__%s", (*iterCCur)->GetName().GetWCharCP(), curECValue.ToString().GetWCharCP());
 mdlDialog_dmsgsPrint(wStr);
 }
 }
	} 
 您可以试着改写成c#的。
