Modeling methods for isogrid design in NX10

Hi,
I would like to model isogrid structure on various surfaces (in my case I need to apply isogrid for two combined conical shapes) in NX10. This structure is with triangular integral stiffening ribs. Ribs need to be perpendicular to the surface.

Here are the examples of isogrid structures:

I am looking for any universal method for this design modeling regardless of surface where need to be applied.

Thank you in advance for any suggestions.
