Select Objects that Intersect a Mesh

Hello All,

I am a relative newbie to Grasshopper. I have a pretty specific question that is more advanced than I can figure out and I haven't found a suitable thread on the internet.

The scenario is: I have a Rhino-generated mesh and a Grasshopper array of boxes. Some of the boxes intersect the mesh and some don't. I am trying to set up a way to eliminate the boxes that do not touch the mesh.

The attached project is a dramatic simplification of the actual problem but I thought it would be more clear.

Any help is more than welcome!

That sounds like it would help, but I dont have the latest Grasshopper and only have Rhino 4.

Im really sorry but that file wouldn't open either. Perhaps I should try to get out of the stone age. I really appreciate your help. Was the solution anything like David's below?

Mesh intersections will be light...

David, that works like a charm!! It was educational for me to start to see how those conditional functions work. I had gotten close but those were the sticking point for me. Thank you very much for your assistance.
