Hello,
Observe this link : https://developer.rhino3d.com/api/RhinoCommon/html/T_Rhino_Geometry_AnnotationBase.htm#fullInheritance
and this : https://developer.rhino3d.com/api/RhinoCommon/html/T_Rhino_Geometry_Dimension.htm
AngularDimension
, LinearDimension
, OrdinateDimension
and RadialDimension
are duplicates.
If you inspect these classes with your IDE, you can understand that these classes are subclasses of the Dimension
class.
but if you read the API page, these classes are defined as subclasses of the AnnotationBase class.
(for example: https://developer.rhino3d.com/api/RhinoCommon/html/T_Rhino_Geometry_AngularDimension.htm)
Thank you.
