plane rotation

[Hemerson Tonin <hemer.tonin@xxxxxxxxxxxxxxx>]

Hi Ferreters,

Has anybody out there a good idea to define axis (and grid) to be inclined ?

I would like to rotate my grid on XY plane, and my "new X-axis" must have 
an angle in relation to Equator.



original  (XY 
plane)                                                            I need 
(XY plane)

                                                                                                            / 
<-- "new X -axis"
                                                                                                           /
-----------> Equator and "current X - 
axis" 
---------/---------------------------- Equator
