If you want to build something large in Minecraft it can take a long time to complete it. But there is a way that can speed things up really fast. You may even construct a village in a few minutes. Just use the clone and fill commands
Build it fast!
You want to build a town with 2 or 3 houses that look the same? It is possible to clone those houses. You must know the x, y and z coordinates and you are half way there already. First check the coordinates of one side of the building for example X0, Y0, Z0. And then the opposite side for example X5, Y5, Z5 and then use this command:
/clone 0 0 0 5 5 5 ~~~
Now the building has been cloned to your current location. You can also replace the last 3 ~ with the destination coordinates. Just remember that the clone will replace whatever was already there.
Out of thin air
If you don’t have a building to clone you can use the fill command. This command fills the targeted area with 1 type of block. This can come in handy if you want to build a great great wall. You can use this command to do so:
/fill 0 0 0 5 5 5 stonebrick
Now the targeted area is filled with stonebrick and whatever was there in the first place is gone. You can also replace all block within the area with another type for example:
/fill 0 0 0 5 5 5 stonebrick 0 replace grass
You can now see that all the grass blocks in this area have been replace with stonebrick but all other blocks remained unchanged. If you want to remove any blog you can use air like this:
/fill 0 0 0 5 5 5 air
This can be helpful but watch out you don’t delete something wrong
