Hi sharonism,
I think of 3D Layer Warp as being able to bend and twist a flexible sheet of paper. The ability to combine three distinct warps on the same “paper” gives you lots of options.
Having said that, it sounds like you have an image of a US map and want to give it thickness or depth. If this is the case, I believe you may want to use Invigorator or ProAnimator. Both can give thickness to an Illustrator-based map. The 3D Warp applications really aren’t designed to do this.
If I misunderstood your post, give us some more details and we’ll try to help out.
