The Polyline annotation object (ANNOBJECT_POLYLINE) is an array of points that create a sequence of joined lines. With the automated functions, each line segment is formed with a mouse click, and the object is completed on a double click.
The class for Polyline Annotation objects is LAnnPolyline.
For information on flipping, reversing or rotating annotation objects, refer to Flipping, Reversing and Rotating Annotation Objects.
With low-level functions, you must provide the points that define the shape of the object. Other applicable properties have the following defaults, which you can change:
