# 12.2 Circle Type Obstacles

#### Adding Circle Obstacles

**Step 1**. When the user selects "**Circle**" as the obstacle type, a screen for adding a point appears. By tapping "**+ Add Point**," the user will create a default-sized circle on the user’s plot, with a yellow point on its edge, just like the screen displays.
