Hello,

I'm having problem with Revit freezes when exporting to IFC and have to force to shut down the program.
The big problem is that it's just one file that I can't export, I have other files wich has a bigger size then this file, contains nearly the same family elements and has no problem.
This is the first time trying to make an IFC-export from this file.
I have tried different kind of settings for the export, I have tried 5 different computers, I have audit the file and tried making a new central model but they all have the same problem. I also have tried upgrade the model to Revit Architecture 2019, it dosen't freeze but I get an error message after a while and it shuts down the program.

Can a file work like charm in Revit but be corrupt for an IFC-export? Or what can be the problem?

Thanks in advance!
