Builder (RFTools)

The Builder is a machine added by RFTools. It consumes Redstone Flux (RF) to construct areas in the world with blocks fed into its inventory or relocating preexisting areas. There are three modes that the Builder can run under: Swap, Move, and Copy, the last of which requires blocks in its inventory. It can be used in conjunction with Space Chamber Corner Blocks and Space Chamber Controller Blocks to designate an area to be built in.

Unless specified with a complex Shape Card, the Builder will draw blocks at random from the supply chest on top. Depending on the choice of materials, the result may appear natural or extremely colorful.

Shape Cards are required to instruct the Builder on where to work.

Clearing Space
Clearing a large volume is easily achieved using the Builder as a quarry. However, you're not limited to rectangular spaces. By configuring the Shape Card to a different shape, the Builder will clear a space of any shape imaginable. If the player wishes to discard blocks gained from clearing with the Builder, they might consider using a Shape Card (Void).

Building a Simple Shape
The player has a Forestry Multifarm that they would like to build a wall around. They would start by programming a Shape Card to create a Hollow Cylinder.



Using the Support/Preview mode in the Builder's GUI, the player then fine-tunes the shape until they obtain the wanted results. Offsets are between the center of the shape and the Builder.



After placing a chest full of Mossy Stone Bricks on top of the Builder and activating the Builder with a Lever, a wall appears within a matter of seconds.



Combining Simple Shapes
The castle pictured below is hardly a masterpiece but it shows what can be constructed in 15 minutes by combining a few simple shapes. With the hard work done by the Builder, a player could use this as the basis for a masterpiece.
