Base Type: Geometry

Derived Types: Path, Polycurve, Segment

An abstract class that serves as a base class for its derived types.


A curve is an abstract one-dimensional geometry between specific from and to points. A curve can be composed of a single Segment, a Path of connected segments, or a Polycurve containing many paths of segments. The properties and methods of the curve allow the user to query information about the entire curve or points along the curve. The distance along the curve can be specified in a fixed unit of measure or as a ratio of the length of the curve.
