The Worldshaper's Sextant is an item added by Botania. It is used to help with building circles.
Holding right-click while looking at a block will set the center of a circle. Looking around while holding right-click will set the radius, displaying a blue circle in the world and its radius near the crosshair. Releasing the right mouse button will replace the circle with fake, transparent cobblestone blocks.
Shift right-clicking with the sextant will remove the circle preview, if one exists.
Filling the entire circle preview with blocks will remove it, displaying a message "Structure Complete!".
