Minecraft wiki entry for Moving_structures_using_structure_blocks_from_world_to_world, associated text: Next, you need two worlds to move the structure you want from one world to another. This requires a structure block, which means you need to have cheats on in that world. If you don't have cheats on, you need click "esc" and click "Open to LAN" to turn on cheats. Type /give @s structure_block in the chat to get the structure block. Next, put the structure block at the north-west corner of your build (a good way to find out the north of your world is to set the time to night and make sure the sun is on your left and the moon is on your right), open it by right-clicking the block, left-click the "DATA" button on the bottom-left until the structure block enters Save Mode, and type in the X, Y, and Z sizes of your structure (you can also detect the structure size if you do not want to type in the sizes so you can use coordinates instead by clicking "alt", "fn", and "f3" together). The bounding box should show up (if you have "Show Bounding Box" on in the structure block) around your structure (or the size you typed in earlier) to see your accuracy of the size. If it is wrong, retype the size until you get the right size for your structure. If you want to save item frames, boats, paintings, or other entities/mobs in your structure, you need to turn "Include Entities" to "on" in the structure block.
