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 2-dimensional, and will only appear on the same y level that the Building Guide is on. Other than these 4 shapes, the shapes are 3-dimensional and dynamic. Using a dye on the Building Guide will turn the guide blocks into the color that the dye is, and will not consume the dye.

Usage
To change the shape of the guide, the sneak key must be held down and an empty hand used on the block. This will cycle through all of the available shapes. To change the size, an empty hand should be used 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.
