Revit二次开发之"复制删除元素"

复制使用ElementTransformUtils.CopyElement();

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

        Transaction ts = new Transaction(uiDoc.Document, "delete");
        ts.Start();

        //选择一个元素
        Reference reference = uiDoc.Selection.PickObject(ObjectType.Element, "请选择第一个对象");
        //复制
        ElementTransformUtils.CopyElement(uiDoc.Document, uiDoc.Document.GetElement(reference).Id, new XYZ(10, 10, 0));
        //删除
        uiDoc.Document.Delete(uiDoc.Document.GetElement(reference));

        ts.Commit();

        return Result.Succeeded;
    }
}
