"Do what specifically? Make a rope?"
to Tom, master of pettifoggery,
Ropes, seams, stitches, decorative lines of any type or source doesn´t matter. How do you it in 3DCoat and how do you get it back into Photoshop with preserved UV map and with bump, normal and displacement maps, all in a layer of its own. And try not to mince words this time and make instead a serious effort to understand my intention.
