Parameters
| center | The center of the circle. |
| normal | The normal of the circle. |
| from | The direction of the point on the circle circumference, relative to the center, where the arc begins. |
| angle | The angle of the arc, in degrees. |
| radius | The radius of the circle Note: Use HandleUtility.GetHandleSize where you might want to have constant screen-sized handles. |
Description
Draw a circular arc in 3D space.
Wire Arc in the Scene View.
