We have recently had several cases come through tech support in which folks were receiving error messages when attempting to edit their families in Revit 2015 R2. The message states "Family <family name here> is corrupt and cannot be edited. Please reload the family to repair the project." Receiving messages such as this one can be a little disconcerting, especially when you are in the middle of a large project. The fear is that the Revit model is corrupt or heading for corruption. In most cases, you may have to look for an archived version of the model or a local file to create a new Central model from, since most corrupt models are difficult to manually repair.
As we discovered, the recent rash of corrupt families within a Revit model has to do when a Revit model was upgraded to Revit 2015 R2. This corruption was more than likely due to the end user not selecting the “Audit” checkbox when opening (or upgrading) their Revit projects for the first time in Revit 2015 R2. Had the “Audit” option been selected, the family corruption issue may not have occurred.
The audit feature in Revit will scan, detect and sometimes fix corrupt elements within a Revit model. So when should you select the “Audit” option?
1. Whenever upgrading a Revit project from one version to another. For example, if you want to upgrade your Revit project from Revit 2015 to Revit 2016, select the “Audit” checkbox prior to opening it for the first time in the newest version.
2. Select the “Audit” checkbox when upgrading ALL models to Revit 2015 R2 for the first time.
3. If your Revit model is starting to take its time opening or you notice general performance issues, then auditing it may improve the time it takes to open your project.
4. If you receive messages such as "Data in file <revit project name.rvt. is corrupt and needs to be manually recovered" or "Family <family name here> is corrupt and cannot be edited. Please reload the family to repair the project."
5. If you are doing any sort of Central File maintenance, including creating new Central Files.
Remember, it is always a good idea to make an archive copy of your model prior to Auditing and Upgrading to the next release of Revit. The reason being is in case the upgrade process introduces errors or corruption issues that cannot be repaired, or if you find a compelling reason to go back and work in the previous version of Revit.
