It isn't clear what the issue is with ExportPoints. You could LMB on ExportPoints2 in the tree outline, then RMB and display the error message. Knowing what the error is might allow modifying the ExportPoints feature options to get it to work.
One solution would be to generate the TurboGrid files in the rotated position using ExportPoints and then modify the points in the profile file to rotate them back to the desired position. The attached pdf shows how this might be done using Fortran. It uses an equation for rotating a point about an arbitrary axis.
Keep in mind that if the blade leading edge camber line is close to or equal to 90 deg with respect to the axis of rotation, TurboGrid may fail.
