Calculate coordinate object when angle rotate project base point.

Hi all,

I have a question for my code by C.# when i get XYZ location for element. But that is a problem when i set angle Angle to true north for project base point, i only get XYZ for Project base point and XYZ for object but this object only follow project base point. How to do i can get XYZ location for object follow Survey Point. Attached image for my question that is how to do from 1, 2 value, can i get 3 value.

the coordinates as reported by Revit using a SpotCoordinate with Coordinate Origin == Survey Point

                XYZ _point = revit.Application.ActiveUIDocument.Selection.PickPoint();

                ProjectLocation pl = doc.ActiveProjectLocation;
                Transform ttr = pl.GetTotalTransform().Inverse;
                XYZ pointRelSurvey = ttr.OfPoint(_point);
