This is a client-side tool for building contraptions with extreme precision, aligning objects for either aesthetic or functional perfection. To accomplish this task a grid is projected onto the object you are pointing at and by pressing the use-button your weapon will lock onto that point and allow you to place objects with pin-point accuracy. For all entities be them square, round or uneven this tool will bring you perfect precision.
