This might not be a answer to your question but have you tried working with maya? It provides a good toolset for smooth surfaces and forms like this. 

 

But that is not of any importance if you want to use rhino and grasshopper :) 

 

Hope you find your answer!

Attached is what I get currently when I model a surface and manually trim out a profile on the surface.

 

 

I did notice that if I use a mesh surface there are a greater amount of vertices to select allowing for a smoother surface, however when i try to trim the profiles to create the opening I no longer can select the mesh surface.

Have you tried using cage edit on a plane? That should generate a smooth surface..

I did do that it still doesn't have the same feel as the one in the picture, I will be placing a voroni pattern from grasshopper on the surface. I just can't figure out how to create a surface similar to the one in the picture. I tried modeling in rhino and in grasshopper:/

I would try to first model the "stingray" shape with cage edit, then boolean or trim/split out the voronoi pattern (you could make a 2d voronoi pattern in grasshopper and lay over the surface). Then I would probably make the different layers with lofts, like the pathways and such. And then blend them somehow if you need it to be one object.

Still trying to figure out how to smoothly join a second surface to this...i.e. a surface that would be a ramp that would bring you up from the ground through the openings :/

I think it looks good! (A bit hard to see on the rendering though ;) )

 

The blend command don't work? Maybe it won't work so good if the surfaces don't have the same length on the blending edges I don't know..
