I cannot get the Tilt About X or Y to insert new tilt angle.  And I would like to read from a .txt to do the same but cannot get the write method to initially set or change the Tilt About X - here is some of my code.

TheLDE = TheSystem.LDE;

%TheLDE.InsertNewSurfaceAt(2);

%TheLDE.InsertNewSurfaceAt(12);

%TheLDE.InsertNewSurfaceAt(5);

Surface_12 = TheLDE.GetSurfaceAt(12);

%Surface_5 = TheLDE.GetSurfaceAt(5);

TheLDE.GetSurfaceAt(12).TiltDecenterData.BeforeSurfaceOrder = ZOSAPI.Editors.LDE.TiltDecenterOrderType.Decenter_Tilt;

TheLDE.GetSurfaceAt(12).TiltDecenterData.BeforeSurfaceTiltX = 5;

TheLDE.GetSurfaceAt(12).TiltDecenterData.AfterSurfaceTiltX = -5;
