# 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.

> #### 🛠️ Adjusting the Size of a Circle-Type Obstacle
>
> 1. **Locate the Yellow Dot** 🟡
>    * On the edge of the circle, find the small yellow dot used for resizing.
> 2. **Enlarge the Circle** ⬆️
>    * To **expand** the circle, **tap and drag** the yellow dot **outward**.
> 3. **Reduce the Circle** ⬇️
>    * To **shrink** the circle, **press and drag** the yellow dot **inward** toward the center.

&#x20;**Step 2**. Once the user has added all the points for the Circle obstacle, tap the "**Save Obs**" button to save it to the user’s plot. The user’s screen will then display the following view.&#x20;
