I tried overlaying the mesh on the box and then using the intersect selection tool but that didnt limit the mesh to the box.
I tried creating an image of the mesh and using it as a texture but when I paint it on the boxs surface, it is not transparent. I tried the 3D Warehouse and could not find any appropriate wire mesh materials. Id like to be able to place the mesh in the box and then have some magic happen wherein the box has the mesh as its fill and be able to see the circle through the boxs mesh.
