How can you get angled fences in Jurassic Park Operation Genesis?

In Jurassic Park: Operation Genesis, angled fences can be created by placing them at an angle rather than in straight lines. To do this, select the fence tool, then click to place the first corner of the fence, and drag it to the desired angle before clicking again to place the second point. This allows you to create a more natural enclosure shape for your dinosaurs. Keep in mind that the game has limitations on how sharply you can angle the fences.
