Polyline Methods

The Polyline type exposes the following members.

Methods
NameDescription
Adds an object to the end of the List.
(Inherited from RhinoListT.)
Adds a Point3d to the end of the list with given x,y,z coordinates.
(Inherited from Point3dList.)
Adds the elements of the specified collection to the end of the List.
(Inherited from RhinoListT.)
Adds the elements of the specified collection to the end of the List.
(Inherited from RhinoListT.)
Constructs a read-only wrapper of this class.
(Inherited from RhinoListT.)
BinarySearch(T)
Searches the entire sorted List for an element using the default comparer and returns the zero-based index of the element.
(Inherited from RhinoListT.)
BinarySearch(T, IComparerT)
Searches the entire sorted List for an element using the specified comparer and returns the zero-based index of the element.
(Inherited from RhinoListT.)
BinarySearch(Int32, Int32, T, IComparerT)
Searches the entire sorted List for an element using the specified comparer and returns the zero-based index of the element.
(Inherited from RhinoListT.)
BreakAtAngles
Breaks this polyline into sections at sharp kinks. Closed polylines will also be broken at the first and last vertex.
CenterPoint
Compute the center point of the polyline as the weighted average of all segments.
Clear
Removes all elements from the List.
(Inherited from RhinoListT.)
ClosestIndex
Finds the index of the point that is closest to a test point in this list.
(Inherited from Point3dList.)
ClosestParameter
Gets the parameter along the polyline which is closest to a test-point.
ClosestPoint
Gets the point on the polyline which is closest to a test-point.
CollapseShortSegments
Collapses all segments until none are shorter than tolerance. This function is significantly slower than DeleteShortSegments, since it recursively operates on the shortest segment. When a segment is collapsed the end-points are placed in the center of the segment.
Contains
Determines whether an element is in the List.
(Inherited from RhinoListT.)
ConvertAllTOutput
Aggregates all results of a conversion function over this table into a new list.
(Inherited from RhinoListT.)
CopyTo(T)
Copies the entire List to a compatible one-dimensional array, starting at the beginning of the target array.
(Inherited from RhinoListT.)
CopyTo(T, Int32)
Copies the entire List to a compatible one-dimensional array, starting at the specified index of the target array.
(Inherited from RhinoListT.)
CopyTo(Int32, T, Int32, Int32)
Copies a range of elements from the List to a compatible one-dimensional array, starting at the specified index of the target array.
(Inherited from RhinoListT.)
CreateCircumscribedPolygon
Create a regular polygon circumscribe about a circle. The midpoints of the polygon's edges will be tangent to the circle.
CreateInscribedPolygon
Create a regular polygon inscribed in a circle. The vertices of the polygon will be on the circle.
CreateStarPolygon
Create a regular star polygon. The star begins at circle.PointAt(0) and the vertices alternate between being on circle and begin on a concentric circle of other_radius.
DeleteShortSegments
Removes all points that are closer than tolerance to the previous point.

Start and end points are left intact.
