I have recently upgraded a 2012 project to 2013 and have had the annoyance of about 30 FCU families now act odd. When I opened the HVAC layouts all the FCUs have moved over to the side. Revit thinks these are all connected fine.
Unfortunately I can’t find a 2012 version now as it has been overwritten (my bad). I have had a similar issue with a grille and that was due to the centre ref lines not defining the origins. In this family the ref lines are defined as the origins. I am at a loss as to how this could happen. Any ideas?

That was the first thing I tried.
In the end I had to start again and replace all the families in the layout.
Please dont select that as a solution. I said it was the first thing i tried meaning it obviously didnt work. I had to start again with a new family and replace all the bugged families in the model.
Your solution did not work.
