Hello fellow Revit users,

I have mad a mechanical equipment family as simple as possible. I'm using it for a MEP project where I have 200 identicals apartments.
Therefor I made a group and I'm now trying to copy the group on view and after on the other levels. When I'm trying to copy the group to the other levels it says "Ducts are disconnected". I have researched a bit and I have found out that the mechanical equipment family is my problem. What am I doing wrong? Why can't I copy it to other levels when it is in a group?

Thank you!
