Syntax
public sealed class EllipticArcBuilder : SegmentBuilder, System.IDisposable  
Public NotInheritable Class EllipticArcBuilder 
   Inherits SegmentBuilder
   Implements System.IDisposable 
Remarks
Use the EllipticArcBuilder class to create and/or modify an EllipticArcSegment shape. An EllipticArcSegment is based upon the parent Segment class. The Segment class is immutable which means that you can not change its shape once it is created. Hence, the EllipticArcBuilder provides the way to make changes when working with an EllipticArcSegment. Use the EllipticArcBuilder.ToSegment method to get the EllipticArcSegment from the builder.

An elliptic arc is the portion of the boundary of a 2D ellipse that connects two points.
