The 3D setting is kind of plug and play once you have the art right (like everything else 
!)
Here’s a great write-up on how to conceptualize the art: Tutorial: 3D Engraving Depth Map Concept, using 2D Design Software
and this post: Anyone know anything about 3d engraving files? links to a Photoshop how-to, and 2 posts down from that links to another site with a guide…
Good luck!
