The Schematica mod is designed for the automatic construction of objects in Minecraft.

So let's get started, go to settings, and look for the key binds.

We will need exactly three buttons at the bottom (Load, Save, Manipulate)

Next, I will take, for example, the structure for summoning bosses from the Cubix Compendium.

- We build the structure manually for the first time.

As soon as the structure is built, click the button to save the schematic, and the settings will appear.

To properly and correctly set up the schematic, there will be an OFF button at the bottom right, change its mode to ON.

Next, define the building areas and how to privatize by selecting two points, the upper and lower if you have a multilayer structure.

The side view looks approximately like this.

As soon as the area is selected, write the name of our new schematic, and press the save button.

Once the schematic is saved, you can turn off the blue-red square display by pressing the ON button again.

Next, press the Load schematic button, and select the name of our schematic in the appearing window and press done.

As soon as you select the schematic, it will appear in our world.

And we proceed to the setup.

Move the schematic to a convenient location for you.

The Materials button - will show how many and what resources you will need to build the structure.

The Unload button - will unload the schematic if, for example, you selected the wrong schematic.

Next, gather all the necessary materials, and press the Printer button; as soon as you enable this function, all you need to do is get closer to the structure, and the blocks will start to be placed automatically in the right places.
