Recently I have manage to create an MEP inline object (a damper) following Graphisoft indications, and I have managed to make it work as expected similar to ArchiCAD native library.
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.
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 ?
