That's clearly a serious of individual panels, raised from the substrate material at different heights. I'd make a flat substrate panel and give it a brass material, then quickly model those squares and rectangles in SketchUp and lay them on top. Would take no time at all!
Thanks for reply. I am not much expert so can you please create this for me and attach sketchup file ( additionally if you can record screen video while creating this and attach that video also i will be highly thankful 🙂)
