Civil 3D surface convertion to Maya polygon mesh?

[eraska]

Hello my friendly CAD Rock Star's,
I'm working on C3D at work and am doing a fairly large surface modle.
I am trying to convert the surface to a polygon mesh so I can import it into Maya.
Since Autodesk bought Maya, I thought I should go to the masters of CAD!!
I bought a 3rd party 3d modle conversion package (Rino 3D) but havn't had much luck.
It works great on converting solid modles but not so well on the TINN's.
Is there another method for converting TINN's to Polygon or nurbs Mesh's?

While working with a surface in C3D, set the display style to show triangles. Then explode the surface. Then explode it again. The first explode creates a block, the second creates independent triangular faces.

Once you have exploded all the way to triangular faces, open the dwg file in Rhino to create a NURBS surface on it.

Rather then expode it twice, go to the menu Surface->Surface Utilities and you can simply extract the 3d faces. Just make sure the surface is set to a style that displays the triangles and you should be good to go.
