Revit二次开发--逻辑或过滤器的使用

今天做嵌套族实例的筛选时，对“常规模型”和“机械设备”均做提取，用到了逻辑或过滤器：
主要代码如下：

	Document familyDoc = doc.EditFamily(family);
        //筛选嵌套族文档中的嵌套实例
        FilteredElementCollector collector = new FilteredElementCollector(familyDoc);
        ElementCategoryFilter filter1 = new ElementCategoryFilter(BuiltInCategory.OST_GenericModel);
        ElementCategoryFilter filter2 = new ElementCategoryFilter(BuiltInCategory.OST_MechanicalEquipment);
        LogicalOrFilter orFilter = new LogicalOrFilter(filter1, filter2);
        collector.OfClass(typeof(FamilyInstance)).WherePasses(orFilter);
        foreach (Element elem in collector.ToElements())
        {
            comboBox1.Items.Add(elem.Name);
        }
