Dim instance As AnnObject
Dim value As Point
 
value = instance.Origin

public:
virtual property Point Origin {
   Point get();
}

Property Value

The logical origin of this AnnObject.

This method returns the logical origin of this AnnObject. This value is calculated by returning the origin of the DefiningGeometry value. You can use this origin to Rotate or Scale this object around itself.
