Public Structure Line
	Implements IEquatable(Of Line)

The Line type exposes the following members.

	Name	Description
	Line(Point3d, Point3d)	Constructs a new line segment between two points.
	Line(Point3d, Vector3d)	Constructs a new line segment from start point and span vector.
	Line(Point3d, Vector3d, Double)	Constructs a new line segment from start point, direction and length.
	Line(Double, Double, Double, Double, Double, Double)	Constructs a new line segment between two points.

	Name	Description
	BoundingBox	Gets the line's 3d axis aligned bounding box.
	Direction	Gets the direction of this line segment. The length of the direction vector equals the length of the line segment.
	From	Start point of line segment.
	FromX	Gets or sets the X coordinate of the line From point.
	FromY	Gets or sets the Y coordinate of the line From point.
	FromZ	Gets or sets the Z coordinate of the line From point.
	IsValid	Gets a value indicating whether or not this line is valid. Valid lines must have valid start and end points.
	Length	Gets or sets the length of this line segment. Note that a negative length will invert the line segment without making the actual length negative. The line From point will remain fixed when a new Length is set.
	To	End point of line segment.
	ToX	Gets or sets the X coordinate of the line To point.
	ToY	Gets or sets the Y coordinate of the line To point.
	ToZ	Gets or sets the Z coordinate of the line To point.
	UnitTangent	Gets the tangent of the line segment. Note that tangent vectors are always unit vectors.
	Unset	Gets a line segment which has Unset end points.

	Name	Description
	ClosestParameter	Finds the parameter on the infinite line segment that is closest to a test point.
	ClosestPoint	Finds the point on the (in)finite line segment that is closest to a test point.
	DistanceTo	Compute the shortest distance between this line segment and a test point.
	EpsilonEquals	Check that all values in other are within epsilon of the values in this
	Equals(Object)	Determines whether an object is a line that has the same value as this line. (Overrides ValueType.Equals(Object).)
	Equals(Line)	Determines whether a line has the same value as this line.
	Extend	Extend the line by custom distances on both sides.
	ExtendThroughBox(BoundingBox)	Ensure the line extends all the way through a box. Note, this does not result in the shortest possible line that overlaps the box.
	ExtendThroughBox(Box)	Ensure the line extends all the way through a box. Note, this does not result in the shortest possible line that overlaps the box.
	ExtendThroughBox(BoundingBox, Double)	Ensure the line extends all the way through a box. Note, this does not result in the shortest possible line that overlaps the box.
	ExtendThroughBox(Box, Double)	Ensure the line extends all the way through a box. Note, this does not result in the shortest possible line that overlaps the box.
	Flip	Flip the endpoints of the line segment.
	GetHashCode	Computes a hash number that represents this line. (Overrides ValueType.GetHashCode().)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MaximumDistanceTo(Line)	Finds the largest distance between this line as a finite segment and another finite segment.
	MaximumDistanceTo(Point3d)	Finds the largest distance between this line as a finite segment and a test point.
	MinimumDistanceTo(Line)	Finds the shortest distance between this line as a finite segment and another finite segment.
	MinimumDistanceTo(Point3d)	Finds the shortest distance between this line as a finite segment and a test point.
	PointAt	Evaluates the line at the specified parameter.
	PointAtLength	Computes a point located at a specific metric distance from the line origin (From). If line start and end coincide, then the start point is always returned.
	ToNurbsCurve	Constructs a nurbs curve representation of this line. This amounts to the same as calling NurbsCurve.CreateFromLine().
	ToString	Contructs the string representation of this line, in the form "From,To". (Overrides ValueType.ToString().)
	Transform	Transform the line using a Transformation matrix.
	TryCreateBetweenCurves	Creates a line segment between a pair of curves such that the line segment is either tangent or perpendicular to each of the curves.
	TryFitLineToPoints	Attempt to fit a line through a set of points.
	TryGetPlane	Gets a plane that contains the line. The origin of the plane is at the start of the line. If possible, a plane parallel to the world xy, yz, or zx plane is returned.

	Name	Description
	Equality	Determines whether two lines have the same value.
	Inequality	Determines whether two lines have different values.
