Building Guide

The Building Guide is a block from the OpenBlocks mod. This block is used to assist the user in building perfect shapes. When placed, it will place ghost blocks in the world, forming the shape and size defined with the block. The available shapes are Cylinder, Cuboid, Dome, Triangle, Pentagon, Hexagon, Octagon, and Sphere. The Triangle, Pentagon, Hexagon, and Octagon are only 2 dimensional, and will only appear on the same y level that the Building Guide is. Other than these 4 shapes, the shapes are 3 dimensional and dynamic.

Usage
To change the shape of the guide, hold down your sneak key and use an empty hand on the block. This will cycle through all of the available shapes. To change the size, use an empty hand on any of the sides. Using the Building Guide on the South face, bottom face, and the West face will make it smaller in that direction. Using the Building Guide on the North face, top face, and the East face will make it larger in that direction. Some shapes, like the Triangle, Pentagon, Hexagon, and the Octagon, cannot have their size changed on just a single side; it will change the size in all directions.
