I see there is a class AsdkHiddenLineBase dealing with hiding lines in dwgs.
Is there any documentation or sample programs that show how to use this feature?
Has anyone used this class to hide lines in dwgs?

Hi All,

I have the same question, 

I suppose that the purpose of this class is to allow custom entities that embedds acis bodies participate to hlr api but I would need clues on how to implement this protocol extension.

Any help would be appreciated.

Thank you
