Method that creates a new EllipticalArc2d object. The object created is a transient mathematical object and is not displayed graphically
| Name | Type | Description |
| Center | Point2d | Input Point2d object that specifies the center of the elliptical arc. |
| MajorAxis | UnitVector2d | Input UnitVector2d object that specifies the direction of the major axis of the elliptical arc. |
| MajorRadius | Double | Input Double that specifies the major radius of the elliptical arc. |
| MinorRadius | Double | Input Double that specifies the minor radius of the elliptical arc. |
| StartAngle | Double | Input Double that specifies start angle of the elliptical arc. The start angle is measured from the major axis vector. |
| SweepAngle | Double | Input Double that specifies the sweep angle from the start angle in a counterclockwise direction. |
