The Elefront “Reference Block By Name” component has options to filter the output.
One of them is “Only Referenced Objects”.
Apart from having the wrong tooltip (the one for the option just above), it also fails to work, like in this case where it fails to list the referenced objects :
I realise Rickson already answered this : the Elefront interpretation of “Referenced objects” is in fact “Attached” elements in a Worksession.
Well that’s a poor choice of words because what GH calls “Referenced” is blocks which actually have an instance in the model.
An the faulty tooltip doesn’t help.
