Rhino for wamit

Hi,
I am using Rhinoceros for to create .GDF file as input to wamit. As per my knowledge Rhinoceros gives me lower order panels. There is option of “patch” in Rhino for the surfaces optional to mesh generation. Can I generate higher order methods in Rhino ? How I can get the NPATCH and IGDEF values of my need?

Thanks,
