判断3D视图{3D}

// 显示或隐藏3D视图中的元素
[Transaction(TransactionMode.Manual)]
[Regeneration(RegenerationOption.Manual)]
// [Journaling(JournalingMode.NoCommandData)]
public   class  HideUnHideIn3DView : IExternalCommand
{
     public  Result Execute(ExternalCommandData commandData,  ref   string  message, ElementSet elements)
    {
        UIDocument uiDoc  =  commandData.Application.ActiveUIDocument;
        Selection selection  =  uiDoc.Selection;

         // 根据Id找到元素的方法
        ElementId elId  =   new  ElementId( 618621 );
        Element el  =  commandData.Application.ActiveUIDocument.Document.get_Element(elId);

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

        Autodesk.Revit.DB.View view  =  uiDoc.Document.ActiveView;
         // 判断是不是3D视图
         if  (view.Name  !=   " {3D} " )
        {
            ts.RollBack();
             return  Result.Cancelled;
        }
         // 判断在此视图下是否可以隐藏
         if  (el.CanBeHidden(view)  ==   true )
        {
            ElementSet elementSet  =   new  ElementSet();
            elementSet.Clear();
            elementSet.Insert(el);

             if  (el.IsHidden(view)  ==   true )

                view.Unhide(elementSet);
            }
