Polyline Methods |
The Polyline type exposes the following members.
Name | Description | |

Adds the elements of the specified collection to the end of the List.
(Inherited from RhinoListT.) | |

Searches the entire sorted List for an element using the default comparer
and returns the zero-based index of the element.
(Inherited from RhinoListT.) | |

comparer and returns the zero-based index of the element.
(Inherited from RhinoListT.) | |

Closed polylines will also be broken at the first and last vertex.
| |
