I wanted to derive a class from AcGiDrawable but the ACRX_DXF_DEFINE_MEMBERS macro is giving the error: C2259: cannot instantiate abstract class. If I override all the pure virtual functions declared in AcGiDrawable, it would no longer be an abstract class?
Any suggestions? Surely this can be done since classes like AcDbEntity implement this class.

Sorry, missed on pure virtual function.
