Class Line

Line class

A polyline is a path defined by a set of points with ControlPoints, and connected by Segments, which means it can also be a set of connected line segments. The line is usually a linear object, which means it cannot be used to represent a curve, in order to represent a curve, uses NurbsCurve.

public class Line : Curve
