Land Mark

The Land Mark is an item in BuildCraft that defines the area that a Quarry, Filler, or Architect Table can work in, with a maximum area of 64x64x64 blocks.

Recipe
The Land Mark can be crafted with one Lapis Lazuli and one Redstone Torch.

Usage
Place two or more Land Marks to specify the area that the machine will use, then right click on the Land Marks to activate them. A red beam frame will show the connected Land Marks. Then place the machine next to one of the Land Marks to create the building frame. The Land Marks will pop out and can be reused again later.

Powering a Land Mark with a Redstone Torch will create a blue beam that helps line up Land Marks to the same axis. This beam will pass through terrain for 63 blocks.
