本文演示如何通过代码，实现Revit中墙的移动，复制，旋转，镜像。

### 1.用Revit绘制墙 ###

### 2.移动 ###

ElementTransformUtils.MoveElement()实现移动功能。

using Autodesk.Revit.Attributes;
    using Autodesk.Revit.DB;
    using Autodesk.Revit.UI;
    using Autodesk.Revit.UI.Selection;
    
    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;
                Selection selection = uiDoc.Selection;
                var eleIds = selection.GetElementIds();
                
                Transaction trans = new Transaction(doc);
                trans.Start("Move");
                foreach (var item in eleIds)
                {              
                    ElementTransformUtils.MoveElement(doc, item, new XYZ(10, 10, 0));
                }
                trans.Commit();     
                return Result.Succeeded;
            }
        }  
    }

执行结果：

### 3.复制 ###

ElementTransformUtils.CopyElement实现复制功能。

ElementTransformUtils.CopyElement(doc, item, new XYZ(10, 10, 0));

执行结果：

4.旋转

ElementTransformUtils.RotateElement实现旋转功能。

ElementTransformUtils.RotateElement(doc, item, Line.CreateUnbound(new XYZ(0, 0, 0), new XYZ(0, 0, 1)), 45.0);

执行结果：

5.镜像

ElementTransformUtils.MirrorElement实现镜像功能。

ElementTransformUtils.MirrorElement(doc, item, Plane.CreateByNormalAndOrigin(new XYZ(1, 0, 0), new XYZ(-40, 0, 0)));

执行结果：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xpeWF6aGVuMjAxMQ_size_16_color_FFFFFF_t_70 4][]
