Revit二次开发 - 构件过滤器（FilteredElementCollector）

    本文演示如何获取Revit文件中的墙类型。

1.用Revit绘制模型

    该模型中包含墙和门。

 

2.获取墙类型

2.1 OfCategory(BuiltInCategory.OST_Walls)

using Autodesk.Revit.Attributes;
using Autodesk.Revit.DB;
using Autodesk.Revit.UI;
using System.Windows.Forms;

namespace RevitAddin3
{
    [TransactionAttribute(TransactionMode.Manual)]
    public class RevitAddin : IExternalCommand
    {
        public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
        {
            UIDocument uiDoc = commandData.Application.ActiveUIDocument;
            Document doc = uiDoc.Document;
            FilteredElementCollector collector = new FilteredElementCollector(doc);
            var walls = collector.OfCategory(BuiltInCategory.OST_Walls);
                    
            string name = "";
            foreach (var item in walls)
            {
                name += item.Name + "\n";
            }            
            MessageBox.Show(name, "信息"); 
            return Result.Succeeded;
        }
    }  
}

   执行结果：

2.2 OfClass(typeof(WallType))

   将语句

 var walls = collector.OfCategory(BuiltInCategory.OST_Walls);

    替换为

var walls = collector.OfClass(typeof(WallType));

   执行结果相同。

2.3 OfClass(typeof(Wall))

    将语句

 var walls = collector.OfCategory(BuiltInCategory.OST_Walls);

   替换为

var walls = collector.OfClass(typeof(Wall));

   执行结果
