The only thing that I didn’t follow Graphisoft instructions was in creating a custom UI for the object, without making the standard call to the macro. And it works fine, except that when I connect the object to the ducts, ConSystem_1 gets messed up. To clarify: As long as ConSystem_1 is not connected to any MEP objects, it shows all related MEP values, once connected, it loses this ability. I need to know why ? And should I make the request to MEP addon instead of depending on the macro ? Author Posts Viewing 0 reply threads The forum ‘Parameter connections’ is closed to new topics and replies.
