Rhino3 & AutoShip problems

Does anyone know how to import a Rhino3 finished polysurface to AutoShip8?
if you export from rhino in gf,iges,dxf format, autoship doesnt read them well
Is there another way?
Case is that i want to run Autohydro.
So if you know another way through modelmaker or straight autohydro (bypassing autoship) its fine with me but every format I have tried seems incompatible
I would appreciate any help on that
p.s. i already have phaser but i want floodable lengthe too so I need a complete suite like autohydro

Can you type in the vertex coordinates in Autoship? that way you can recreate your Rhino3D surface in autoship, read the Surface vertex from rhino and then type in autoship, that may be the closest way to do it. if is not so big.
