The protractor annotation object (ANNOBJECT_PROTRACTOR) consists of two simple lines joined at a vertex to create an angle. With the automated functions, the first line of the protractor is started on a mouse-down event and completed on a second mouse-down event. The second line is completed on a third mouse-down event.
For information on flipping, reversing or rotating annotation objects, refer to Flipping, Reversing and Rotating Annotation Objects.
With low-level functions, you must define the size and position of the rectangle. Other applicable properties have the following defaults, which you can change:
