Syntax
public sealed class LineBuilder : SegmentBuilder, System.IDisposable  
Public NotInheritable Class LineBuilder 
   Inherits SegmentBuilder
   Implements System.IDisposable 
Remarks
Use the LineBuilder class to to create and/or modify a LineSegment shape. A LineSegment 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 LineBuilder provides the way to make changes when working with a LineSegment. Use the LineBuilder.ToSegment method to get the LineSegment from the builder.

A line segment is a straight line between a start point and an end point.
