`ToX` Full Usage: `ToX` Field type: `float`	Returns the X coordinate of the end point of the line. Field type: `float`
`ToY` Full Usage: `ToY` Field type: `float`	Returns the Y coordinate of the end point of the line. Field type: `float`

Constructors

Constructor	Description
`Line2D(fromX, fromY, toX, toY)` Full Usage: `Line2D(fromX, fromY, toX, toY)` Parameters: fromX : `float` fromY : `float` toX : `float` toY : `float` Returns: `Line2D`	Create Line2D from 2D start point's x and y and 2D end point's x and y . fromX : `float` fromY : `float` toX : `float` toY : `float` Returns: `Line2D`
`Line2D(fromPt, toPt)` Full Usage: `Line2D(fromPt, toPt)` Parameters: fromPt : `Pt` toPt : `Pt` Returns: `Line2D`	Create Line2D from 2D start point and 2D end point. fromPt : `Pt` toPt : `Pt` Returns: `Line2D`

Instance members

Instance member	Description
`this.AsString` Full Usage: `this.AsString` Returns: `string`	Format 2D line into string from X and Y for start and end points. Using nice floating point number formatting . But without full type name as in v.ToString() Returns: `string`
`this.Direction` Full Usage: `this.Direction` Returns: `Vc` Modifiers: inline	Same as ln.Vector or ln.Tangent. The returned vector has the same length as the Line2D. Returns: `Vc`
`this.From` Full Usage: `this.From` Returns: `Pt` Modifiers: inline	The Start point of the 2D Line2D, Returns: `Pt`
`this.Length` Full Usage: `this.Length` Returns: `float` Modifiers: inline	Returns the length of the line. Returns: `float`
`this.LengthSq` Full Usage: `this.LengthSq` Returns: `float` Modifiers: inline	Returns the square length of the line. Returns: `float`
`this.Tangent` Full Usage: `this.Tangent` Returns: `Vc` Modifiers: inline	Same as ln.Vector or ln.Direction. The returned vector has the same length as the Line2D. Returns: `Vc`
`this.To` Full Usage: `this.To` Returns: `Pt` Modifiers: inline	The End point of the 2D Line2D, Returns: `Pt`
`this.UnitTangent` Full Usage: `this.UnitTangent` Returns: `UnitVc` Modifiers: inline	Returns a unit-vector of the line Direction. Returns: `UnitVc`
`this.Vector` Full Usage: `this.Vector` Returns: `Vc` Modifiers: inline	Same as ln.Tangent or ln.Direction. The returned vector has the same length as the Line2D. Returns: `Vc`
