    {

        UIDocument uiDoc = cmdData.Application.ActiveUIDocument;

        Transaction ts = new Transaction(uiDoc.Document, "SetFamily");

        ts.Start();

        FilteredElementCollector collector = new FilteredElementCollector(uiDoc.Document);

        collector.OfCategory(BuiltInCategory.OST_DuctFitting);//过滤出来系统包含的Symbol与文档包含的Instance

        //collector.OfClass(typeof(FamilyInstance)).OfCategory(BuiltInCategory.OST_DuctFitting);

        int iSymbol = ;

        int iFi = ;

        foreach (Element el in collector)

        {

            if (el is FamilySymbol)

                iSymbol += ;

            else if (el is FamilyInstance)

                iFi += ;
