problem drawing axial velocity in tecplot
 

hi
i want to draw a axial velocity along center line at constant plane (for example y=0.5) . i have a 3D curved pipe . how can i draw axial velocity and pressure in tecplot 360?
can any told me how to convert cartesian coordinate into toroidal or cylindrical coordinate?
i solve the problem with fluent and load data in tecplot..
