The recipe for a quarry
A builder is a machine that, when powered, will automatically build a structure based off a Blueprint, using resources supplied by the player. As a note, the blueprint does include the types of blocks in the original template, different from the way this worked in buildcraft 2. Once placed, a stone pick or greater is required to retrieve the builder.
Usage[]
The Builder GUI
Place the builder in your world, and right click on it to display the builder interface. Place a Blueprint into the template slot.?
The builder area assigigning shown in game
The area that the Blueprint uses will be displayed in the world so you can adjust the position of the builder if needed.
A builder in action
Put some resources into the builder, and supply some power, and the builder will automatically build the structure from the template. A steam engine or greater can power a Builder. 2 green status combustion engines burning fuel are required to fully power the builder. At this power level, the builder will place approximately 350 blocks a minute, or 5 and a half full stacks. If there is something in the area already, the builder will either remove it if it is not part of the template, or leave it there if it is. Blocks removed this way will remain on the ground, they will not pop out of the builder.
