这里涉及到一些专业术语Face,Plane,UV，还没搞清楚，暂时记录下来。

1. 
   
2. <div align="left" style="color: rgb(105, 105, 105); font-family: 'Microsoft Yahei', Simsun; ">[Transaction(TransactionMode.Manual)]
   
3. [Regeneration(RegenerationOption.Manual)]
   
4. public class cmdMirrorWall : IExternalCommand
   
5. {
   
6.     public Result Execute(ExternalCommandData cmdData, ref string msg, ElementSet elements)
   
7.     {
   
8.         UIDocument uiDoc = cmdData.Application.ActiveUIDocument;
   
9. 
   
10.         Transaction ts = new Transaction(uiDoc.Document, "http://revit.5d6d.com");
    
11.         ts.Start();
    
12. 
    
13.         Reference reference = uiDoc.Selection.PickObject(ObjectType.Element, "选择一面墙");
    
14.         Wall wall = uiDoc.Document.GetElement(reference) as Wall;
    
15.         MirrorWall(uiDoc.Document, wall);
    
16. 
    
17.         ts.Commit();
    
18. 
    
19.         return Result.Succeeded;
    
20.     }
    
21.     private void MirrorWall(Document doc, Wall wall)
    
22.     {
    
23.         Reference reference = HostObjectUtils.GetSideFaces(wall, ShellLayerType.Exterior).First();
    
24.         Face face = wall.GetGeometryObjectFromReference(reference) as Face;
    
25.         UV bboxMin = face.GetBoundingBox().Min;
    
26.         Plane plane = new Plane(face.ComputeNormal(bboxMin), face.Evaluate(bboxMin).Add(new XYZ(10, 10, 0)));
    
27.         ElementTransformUtils.MirrorElement(doc, wall.Id, plane);
