Description

using UnityEngine;
using UnityEditor;

// draw a red circle around the scene cube

[CustomEditor(typeof(CubeExample))]
public class CubeEditor : Editor
{
    void OnSceneGUI()
    {
        CubeExample cubeExample = (CubeExample)target;

        Handles.color = Color.red;
        Handles.DrawWireDisc(cubeExample.transform.position, new Vector3(0, 1, 0), cubeExample.circleSize);
    }
}

using UnityEngine;

public class CubeExample : MonoBehaviour
{
    public float circleSize = 3.0f;
