- This page is about the Blueprint added by BuildCraft. For other uses, see .
The Blueprint is an item used to remember the shape and materials of a structure for automatic building. In a Builder, the exact type of materials used in the Blueprint must be present. This is unlike the Template which will not remember the type of blocks used.
After designing a structure in the Architect Table, name the Blueprint using the middle bar. Then place a blank Blueprint into the left slot. If the Blueprint is unnamed, it will be numbered automatically instead.
In a Builder, place the Blueprint into the left slot and place the specific blocks required into the Builder's inventory. The Builder will only build if it has the materials that were originally designed.
