Recovering a Corrupted or Upgraded Central Model
BIM Suite · How to Recover a Corrupt Central Model · 4m
This lesson covers the process of recovering a central model in Revit that has become corrupted or mistakenly upgraded. You will learn how to identify the most recent local model, retrieve it, and recreate the central model from that local file.
Specific skills include navigating file locations to access local models, detaching the local model from the central, and saving it as a new central model while preserving worksets. This practical approach ensures minimal loss of work and restores project continuity efficiently.

You might need to recover a central model for one of two reasons. One, someone may have accidentally upgraded the central model to a newer version of Revit. They may have opened 2023 model in 2025, for example, or the model may just have become corrupted for any variety of reasons, and you need to go in there and you need to recover the central model. So of course one way to do that is to right click the file, restore previous versions. If you have that set up, your IT department might have something else set up.
You might be able to do that. However, you should also know that you can recreate the central model from users local models. Particularly if a user has been working in a local model and it's been a while since they've synced and then the central model corrupts or got upgraded and they've got a lot of work that they've done on their local model, there might be more work done in that local model that they've got that was never synced to the central model than the most previous good version of the central model. So it might make more sense to recreate the central from that local model. Here's how to do it.
First, you've got to go around your office, figure out who had the likely most recent saved version of the local model with the most up to date work in it. That might be a judgment call, you just have to go around and talk to people. Once you do, go to go to the user's computer that has the latest version of the local model you suspect, and you wanna go and get their local model. How to do that? Well, go to Revit, go to file, go to options, go to file locations, and it will have a default path for user files.
This is where mine is. Your users might be different. Copy that path, go to file explorer, paste it in there, and here is where the local model exists. So if they're still in Revit, have them save their local model. It will save this.
All their work will be up to date, and then they can update the version of the central model. So what you do on the local users machine, grab this, grab the local, go back to the project x folder. I'm just gonna paste that there. I'm going to append to this with old corrupted central and push it to the archive folder. So I've just gotten completely rid of it.
I'm going to take that out of there. Okay. And then I'm going to go to Revit. And now I've just moved a local model here, so I've got to recreate this as a central model. So I'm going to do detach from central.
I'm going to open detach and preserve worksets is fine, then file, save as, project, and you'll see Revit wants to append underscore detach to it. Single click the model here that you want to become central, and you can come to options to verify for yourself that Revit will make this a central model after save. Hit save. Yes. And now you've created the new central model, you are in it, so if you want to keep working, the first thing you want to do is get out of it, then you could go back and create a new local and hop back into it, and everyone else also can now get back into the newly restored central model.
