Access LinearDimension geometry in C#

Hi,

I’m trying to access the geometry of a LinearDimension with the Explode() method, which rhinocommon says is inherited from AnnotationBase. However, the AnnotationBase class doesn’t seem to have this method. Is this a typo in RhinoCommon? Is there any other way to access the curves and text object of a linear dimension?

thanks
Oliver

Where do you see this?
