                    }
                }
            }



            Transaction transaction = new Transaction(document, "xx");
            transaction.Start();

            BoundingBoxXYZ bounding = view3d.CropBox;


            view3d.CropBox = bounding;

            view3d.CropBoxActive = true;
            view3d.CropBoxVisible = true;

            transaction.Commit();

            return Autodesk.Revit.UI.Result.Succeeded;

        }

    } //end of class    
} //end of namespace

 As above code , the result is strange, the view turned to a blank view, seems that the direction of the camera/eyesight changed inverse. But the result is right is the view "Aerial" is  an isolated Isometric View,

How it happens?

I had a similar issue when modifying the cropbox of an elevation view and also experienced the inverse effect.  See following post:

Joe.Ye was going to feed this back to the delopment team.
