The Polyline2 and Polyline3 classes provide the same constructors, properties, and
methods. They vary only in the dimensions available. Polyline2 objects are constructed
from Point2 objects and Polyline3 objects are constructed from Point3 objects. The
following section details the constructors, properties, and methods available using the
Polyline3 for the examples.
Each Polyline type has multiple constructors. Using Polyline3, for example, here is the
constructor that takes a set of points:
Point3 [] points = ...;
Polyline3 polyline = new Polyline3(points);
This example creates a Polyline3 from a collection of points and specifies if the polyline
is closed or not.
bool isClosed = true;
Point3 [] points = ...;
Polyline3 polyline = new Polyline3(points, isClosed);
The public properties for Polyline include:
IsClosed - This property returns true if the polyline is closed.
IList points = new List();
points.Add(new Point3 (0, 0, 0));
points.Add(new Point3 (1, 1, 1));
points.Add(new Point3 (2, 2, 2));
Polyline3 poly1 = new Polyline3(points);
Polyline3 poly2 = new Polyline3(points,true);
bool result = poly1.IsClosed;
//result is false;
result = poly2.IsClosed;
//result is true;
The Polyline class defines the public field:
Empty – This method defines an empty polyline (with no points).
Polyline3 poly4 = Polyline3.Empty;
