Floors repeatedly disappear from the model after synching

[gabriella_scotto92]

Hello everyone ! 

I am working on a shared Revit model with 2 other persons and we all created local files related to the central model. Multiple times some of our floors completely disappeared from our model after we synched. It seemed that one person would have it disapeared in their local file and the problem would "spread" to the others after the synchronization. 

The strange thing is, this problem only occured with a number of specific floor instances belonging to the same family therefore we suspect it could be related. 

We tried to apply the recommendations made by Autodesk on the related article wihtout success. We are concerned that this problem would grow and affect more elements and would like to understand and solve it. 

Thank you in advanced for any help or suggestions ! 

Gabi.

Hi ! Thank you, we already tried but nothing improved unfortunately

If you tried all the solutions in the article, I would just make a new central model by detaching or etransmit. Start fresh and see if it continues to happen. If it does, there might be a corrupt element in the model.
