mdlLevel_getIdFromElementIdH

Hi,

I currently doing a migration from v8i to V10 (CONNECT).

I need a substitute for mdlLevel_getIdFromElementId, which is not part of the API any more.

Any suggestions?

Best, Stefan.

    In the help documentation for ElementPropertiesGetter there is an example that may help.

    However, as with much of the MicroStationAPI documentation, it's hard to find.  You need to look in the Detailed Description section, then click the rather dim More... button to see that example.

    static void getLevelAndColor (ElementHandleCR eh, LevelId& level, UInt32& color)
    {
    ElementPropertiesGetterPtr propGetter = ElementPropertiesGetter::Create (eh);
    level = propGetter->GetLevel ();
    color = propGetter->GetColor ();
    }

  • Thanks for responding John,

    but its not exactly what I need.

    The old function returned the levelid from an element that has stored the level definition in it.

  • Hello stefan,
    I'd like to know the situation you use this function. How you get the level element ? Normally we specify a level by its name. The level name is unique in a DgnFile.

  • Hi YongAn,
    The level element is coming from a full dgn file scan. By its element type the software knows its a level element and tries to extract the level properties.
    Best, Stefan.
  • Hello Stefan,

    Normally, in V8i, we use mdlLevelIterator_create/mdlLevelIterator_getFirst/mdlLevelIterator_getNext/mdlLevelIterator_free to traverse all levels in a DGN file. In CONNECT, we can use LevelCache to do this. The following snippet is my test code to list all levels and its materials. Hope it is helpful.

    void listLevel(WCharCP unparsed)
        {
        WString myString;
        DgnModelP pActiveModel = ISessionMgr::GetActiveDgnModelP();
        LevelCacheCR lvlCache = pActiveModel->GetLevelCache();
        for (LevelHandle lvlHandle : lvlCache)
            {
            WCharCP pLvlName = lvlHandle.GetName();
            LevelDefinitionMaterial lvlMat = lvlHandle.GetByLevelMaterial();
            //LevelDefinitionMaterial lvlMat2 = lvlHandle.GetOverrideMaterial();
            ElementId elId = lvlMat.GetId();
            if (INVALID_ELEMENTID != elId && 0 != elId)
                {
                MaterialSearchStatus matStatus;
                DgnFileP pMatDefFile = lvlMat.GetDefinitionFile();
                MaterialId matId(elId);
                MaterialCP pMat = MaterialManager::GetManagerR().FindMaterial(&matStatus, matId, *pMatDefFile, *pActiveModel, true);
                if (matStatus == MaterialSearchStatus::Success)
                      myString.Sprintf(L"%s | material=%s", pLvlName, pMat->GetName(NULL));
                else  myString.Sprintf(L"%s | Can't find material", pLvlName);
                }
            else myString.Sprintf(L"%s | No Material", pLvlName);
            mdlDialog_dmsgsPrint(myString.GetWCharCP());
            }
        }
