Parameters

center

Vector3
The center of the circle.

normal

Vector3
The normal of the circle.

from

Vector3
The direction of the point on the circumference, relative to the center, where the sector begins.

angle

float
The angle of the sector, in degrees.

radius

float
The radius of the circle

Solid Arc in the Scene View.

Examples

using UnityEditor;using UnityEngine;static class ArcExample{    static Vector3 m_Angle = new Vector3(1.5f, .66f, 0f);    // Create an arc at 0, 0, 0 in the Scene view and a slider that changes thes angle of the arc.    [InitializeOnLoadMethod]    static void Init() => SceneView.duringSceneGui += view =>    {        Handles.DrawLine(new Vector3(1.5f, 0f, 0f), new Vector3(1.5f, 1f, 0f));        var handleSize = HandleUtility.GetHandleSize(m_Angle) * .1f;        m_Angle = Handles.Slider(m_Angle, Vector3.up, handleSize, Handles.DotHandleCap, EditorSnapSettings.move.x);        m_Angle.y = Mathf.Clamp(m_Angle.y, 0f, 1f);        Handles.Label(m_Angle + Vector3.right * handleSize * 2f, $"Angle {m_Angle.y * 360f}");        Handles.DrawSolidArc(Vector3.zero, Vector3.forward, Vector3.up, m_Angle.y * -360f, 1f);    };}
