macro for axis system

What is the step by step procedure to create a macro for the global axis system. I need the global Z axis to point towards the sea floor (Z axis vertical and down, and XY horizontal). Regards and thanks in advance for any help. Juan

The global axes could not be changed.
I assume that do you mean to change the view
Write this in the lower command line:

'Rotate Angle 270 180

(or put it in a macro toolbar button with “GiD_Process 'Rotate Angle 270 180”)
