Hi everyone,

I created some 2D Truchet tiles and I want to make them into a 3D carved surface like in the images attached.

Can someone please guide me on how to achieve that smooth 3D carved look from the 2D pattern?

Thanks in advance for your help! :folded_hands:t4:

I’m nort sure if this is what you want. If so, you can achieve it with Shrinkwrap,

Good but looking at the image reference the extrude should not just been an extrude I don’t know if I can use tapered extrude to achieve that
