Pools can be built using the pool tool. After selecting the pool tool, a pool path can be drawn. While drawing the pool path, holding down the Shift key will allow drawing diagonal pool edges. Pressing the Esc key while drawing a pool will cancel the current pool path.

After the pool path is complete, the pool edges can be shaped using the pool studs. Note that the pool path cannot self-intersect.

Properties: Various properties of pools can be set before creating a pool or if a pool is selected.
