The protractor annotation object (AnnProtractorObject) 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.
Programmatically, the boundaries and location of the protractor object can be controlled using the following properties:
The AnnProtractorObject class inherits a number of properties from the AnnObject class that provide support for font, pen and brush characteristics. These properties are listed below:
The AnnProtractorObject class implements the IAnnProtractor interface. This interface provides a number of protractor properties that control certain aspects of the protractors themselves and indicate which characteristics will be displayed on the protractor. These properties are listed below:
The AnnProtractorObject class implements the IAnnRuler interface. This interface provides a number of ruler properties that control certain aspects of the rulers themselves and indicate which characteristics will be displayed on the ruler. These properties are listed below:
- GaugeLength
- MeasurementUnit
- Precision
- IsRulerImplemented
- ShowGauge
- ShowLength
- ShowTickMarks
- TickMarksLength
- UnitAbbreviation
The name of the protractor object can be controlled using the following properties, inherited from the AnnObject class:
