migrating files from AECOsim SS6 to OBD connect

i need to import mechanical files from AECOsim SS6 to OBD connect Update 6

when i have tried copying the elements into the ODB file i get this message

does this mean that pipework or ductwork modelled using the aecosim applications are not compatible and need to be re-modelled from scratch?

is there a patch or work-around?
