public interface ILcdArc
extends ILcdShape
```
An ILcdArc is an ILcdShape that represents a general elliptical arc in the 2D space. All of its points lie at on an ellipse with a center, a semi-major axis with a rotation angle, and a semi-minor axis. The arc starts at a start angle and extends over an arc angle.
The parameters of the arc can only be read, not modified.
