It is very common for pool manufacturers to build their pools with different numbers of angled sections to make up the pools outer edge. We have general plans that consist of mostly 18 or 24 sections depending on pool size. These plans will work for most pool designs even if the pool has more or less angles than the plan. We recommend you build the deck as the plans show, it is much simpler than trying to modify the plans to match the amount of sections your pool has. When it is all assembled no one will ever know the difference.
