Revit二次开发之“元素的移动MoveElement()”

对元素的基本操作，比如镜像，偏移，移动，复制等，都是通过ElementTransformUtils类。

[Transaction(TransactionMode.Manual)]
[Regeneration(RegenerationOption.Manual)]
public class cmdMove : IExternalCommand
{
    public Result Execute(ExternalCommandData cmdData, ref string messages, ElementSet elements)
    {
        UIDocument uiDoc = cmdData.Application.ActiveUIDocument;

        Transaction ts = new Transaction(uiDoc.Document, "revit.5d6d.com");
        ts.Start();
        //这里好像只能选择一个族实例，比如弯头，风管就不行。
        Reference refelem = uiDoc.Selection.PickObject(ObjectType.Element, "选择一个元素");
        Element elem = uiDoc.Document.GetElement(refelem);
        //当前位置
        LocationPoint elemLocation = elem.Location as LocationPoint;//familyInstance.Location;
        XYZ oldPlace = elemLocation.Point;
        //新位置
        XYZ newPlace = new XYZ(10, 20, 30);
        ElementTransformUtils.MoveElement(uiDoc.Document, elem.Id, newPlace);
        //
        elemLocation = elem.Location as LocationPoint;
        XYZ newActual = elemLocation.Point;
        string info = "Original Z location:" + oldPlace.Z
            + "\nNew Z location:" + newActual.Z;
        TaskDialog.Show("revit.5d6d.com", info);

        ts.Commit();

        return Result.Succeeded;
    }
}
