Revit Cloud Model Maintenance

February 21, 2019 Cherisse Biddulph

This blog shows you what to do if you keep getting errors that your elements/data is corrupt in your cloud model.  There are two ways to go about this; one is to clean up the model which should be done frequently and the other is to find a backup of the corrupt model.

Revit Cloud Maintenance

How to find your local cloud model:

1.  Make sure all users in the cloud model have synced their work, relinquished, and closed their model.

2.  The user who initiated the Collaborate for Revit on the model needs to publish the model so it will be updated on the BIM 360 website. Here is how to publish your model: How to publish your Revit model .  

3.  Ensure everyone who is working on the project is on the latest build.

4.  Have all users find their local cloud model file and archive or move it. To find your local cloud model follow the steps below:

  • Identify the Project and Model GUID for the affected model:
    • Open a recent journal file in NotePad.

All Journal files are located in C:\Users\user profile folder\AppData\Local\Autodesk\Revit\Autodesk Revit 20XX\Journals folder. * AppData is a hidden folder. Here is Microsoft's steps on how to show hidden folders: https://support.microsoft.com/en-us/help/14201/windows-show-hidden-files

  • First find the projects GUID. Use the find tool to search for CLD. It will look like this; CLD:\\{Project GUID with numbers and dashes}(Project Name)\{Model GUID also with numbers and dashes}(Model Name).rvt. Write down the project and model name GUID.
    • For example my local from the project called 2019 RAC would show in the journal as: "CLD:\\{df5ac47f-ccdc-491d-a8ad-4e73a7780c58}(cbiddulph) Revit 2019\{ad832dfc-b89a-48f0-a9d9-8980515a8a69}2019 RAC.rvt".
  • Next find the location of the project folder using NotePad’s find tool to search for; SLOG  Local (double space between slog and local)
    • For example my path is "C:\Users\cbiddulph\AppData\Local\Autodesk\Revit\Autodesk Revit 2019\CollaborationCache\200804142022663\df5ac47f-ccdc-491d-a8ad-4e73a7780c58\ad832dfc-b89a-48f0-a9d9-8980515a8a69.rvt"
  • Move the entire model folder in the CollaborationCache folder to another location (e.g. the Desktop or network)

5.  Delete as much as you can from the temp folder located here: C:\Users\your user profile folder\AppData\Local\Temp. If something will not let you delete it click Skip. *AppData is a hidden folder. Here is Microsoft's steps on how to show hidden folders: https://support.microsoft.com/en-us/help/14201/windows-show-hidden-files

How to perform maintenance on your cloud model

1.  Once everyone's locals are moved, download the model from the BIM 360 site.

2.  Open the downloaded cloud model with Audit checked.

Resaving cloud model to the cloud

3.  When you have confirmed the model opens without errors and any linked in models are loading without issues you can now go back to the BIM 360 site and do one of the following: Delete the model within the project, rename the model and create a new folder and move it. You can remove permissions to view the folder so others can't see it.

4.  Perform a Revit model maintenance and save the model to your desktop or company network. Here is our blog on Revit central file Maintenance

5.  With your clean model you can now run the Collaborate command to save it to the cloud with the original file name. Once its successfully on the cloud you can have everyone open the model which will create a new local and test by running a sync to central.

How to recover a corrupt cloud models that will not open

If your model can't be recovered by:

You will need to submit the model to Autodesk or your reseller so they can get the model fixed. 

Once you get your model back from your reseller or Autodesk you will do the following:

1.  On the BIM 360 website you can delete or rename the old model and move it. This will ensure that no one accidentally works on it.

2.  Find your local cloud model files and delete or archive them.  See the above steps on how to find your local model.

3.  Inside Revit open your clean model.

4.  Perform the Collaborate command.

5.  Since you deleted or renamed and moved the old corrupt model on the BIM 360 site you can keep with the same naming convention in the same project folder.

6.  Once you have successfully collaborated the model to the BIM 360 site you can now close the model by syncing to central. Have your users open the model and verify they too can sync to central with no issues.

Follow the above steps to keep your file clean and make sure everyone who is working on the project (both inside and outside your company) has their Revit updated to the latest build.
