How to access your Autodesk subscription?

By now you may have heard that Autodesk is fully adopting the Named User Subscription licensing model and ending support for multiuser or network licenses as well as the need for serial numbers. Your subscription is now associated with your email address and Autodesk ID (If you want to know more about the Transition to Named User, click here).

In this article, I’ll be explaining where you can go to access your Autodesk account and subscription.

You can access your software through your Autodesk Account, which you can find at

If you have a license assigned to you, you’ll be able to access the software and subscription services under “All Products and Services” What we see in the image below is the navigation bar on the left-hand side of the Autodesk account.

If you’re an administrator or contract manager, your Autodesk account will look a bit different, as you’ll be able to access the User Management tab as shown in the screenshot below. There you can add users and assign licenses right to your Autodesk account. To learn more about managing the users in your firm, inviting other administrators to your account, and controlling users’ access to specific software and services, check out Setting Up your Autodesk Software Subscriptions.


At this point, you’ve logged in and had the ability to access the Products and Services you’re managing or those that are assigned to you.

Don’t hesitate to call our support team if you have any further questions or concerns. We’re here to help. While you’re still in the Autodesk account, you can also click on the questions mark if you want to learn more from Autodesk.

Revit Error: Too Many Elements Missing

Model corruption in Revit can happen. We noticed a common trend about what causes these issues and have compiled possible solutions to implement into your project or firm’s workflow, to reduce the risk of corruption and down-time. In another article we’ve discussed, What Causes Revit Data Corruption? In this article, we will focus on one of the worst instances of model corruption.

“The model {filename}.rvt is missing many elements, and cannot be opened.”

This error indicates corruption in Arch, Struct, or MEP Revit families, where the application does not allow anyone to open the project file. This can affect both projects using or not using Worksets and Worksharing. This message appears when there are more missing elements than Revit will ignore. If there are just a few missing elements, Revit ignores them and attempts to continue opening the model. If there are too many missing elements, the file is unrecoverable and the team will have to restore a previous version of the file or a local file.

There are instances where the Microsol Resources support team can open a case with Autodesk and have the file repaired. Sadly, this does not happen often.

However, sometimes the error only occurs when the ‘audit’ option is checked when opening the file. We will proceed with the understanding that we are able to open the model and that the error appears when ‘Audit’ is checked.

The following are two images of the error message we’ve seen.

Old Message


Revit Error & Possible Causes

Elements in your project are corrupt, causing Revit to report the missing elements.  Here is our tutorial on troubleshooting.

  1. Collect backup files for your local and detached central.
  2. Identify the elements. In the Revit Journal for this session, it is common that the families causing the issue can be identified.
  3. The element corruption may exist in a linked RVT.
    If the linked file has many missing elements and the link cannot be loaded, Revit may present the missing elements warning.
  4. One user is running a different build of Revit.
    They have not installed the same updates that the rest of the team is using.
  5. Packet Loss
    A communication interruption between the local file and the central file. Most likely due to poor internet or network connection.
  6. Too many warnings
    Try to minimize warnings to the best of your ability, especially the following warnings:

    • Any error that indicates a problem that will affect area or volume calculation. Volume requires much more calculation than area.
    • Highlighted walls are attached to, but miss, the highlighted targets
    • Highlighted elements are joined but do not intersect
    • Area or Room separation line is slightly off-axis and may cause inaccuracies
    • Highlighted lines overlap. Lines may not form closed loops and it’s variations
    • Stair errors.
    • Duplicate and Overlapping Elements.
  7. Upgrading an old model/family
    Up until Revit 2016, there were certain elements that ended up getting their IDs changed in 2017. Things like fonts and stairs/railings, in particular, got changed and caused a lot of issues.
Possible Solutions
  1. Open the model without Audit Check
  2. Identify the missing elements
  3. Replace the missing elements from a backup or stable file.
  4. Export Families using Save as / Save as Family / Save as Library
  5. Import families that illustrate errors during the Save as Library process.
  6. Find a user with a working local copy, or the most recent backup without the error, and move forward with the recovered model.

The premise is that this error is caused by one or more corrupt family components. So the solution is to extract all families from an un-corrupted archive of the model (un-corrupted here means that one is able to open the model with an ‘Audit’ check) and load those families into the corrupted version of the model. This overwrites all family definitions including corrupted versions and thus rids the project of the error. Family extraction from a project can be automated by going to Save As > Library > Family.  We need to find a stable family or repair the issues identified in this warning.

The image below was captured during this process, a warning pops up indicating the family is problematic in some way. I moved the warning error box to the lower left of the Revit interface, in order to see and capture the warning next to the status bar. This information and the right Revit journal file can help identify potential problems in the family being exported.

The warning dialog has an option to export the warning, the element ID, and the addressable issue.

However, the challenge with this approach is that large projects contain hundreds of families, and loading them manually becomes tedious. We can automate the process either by using a macro or a dynamo script. Reach out if this is something your team needs.

Once the corrupt family has been identified, one can re-open the model and locate the family in the Project Browser and delete the family (via right-click), or replace the family with an un-corrupted version from the library or archive.

The project should open without error after this (when ‘Audit’ is checked). If there is more than one corrupt family, this process will have to repeat as many times as needed since each run of the Family Size Reporter will crash when processing the first available corrupt family.

Missing Elements Hosted on BIM 360

If the missing elements message is received for a Cloud Workshared model hosted on BIM 360, then the process would be the same (restore a previous version of the model and replace any family corruption). However, the corruption could be isolated to the locally cached copy of a model or link, particularly if the issue is limited to just one user. In this circumstance, the solution is far simpler:

To clear a corrupt/damaged cloud workshared model or outdated link from the system:

    1. Create a folder called Cache on the Desktop.
    2. Move the PacCache and CollaborationCache folders to the folder created on the desktop.
      • Collaboration cache folder location C:\Users\%USERNAME%\AppData\Local\Autodesk\Revit\Autodesk Revit ####\CollaborationCache
      • PacCache folder location C:\Users\%USERNAME%\AppData\Local\Autodesk\Revit\PacCache
    3. Open the problematic file in Revit.
      • Note: This will recreate the cache and clear any corrupt/damaged cloud workshared cache data.
    4. Open the Desktop folders from Step 2 and the original folder location of the Cache files.
    5. Move the files that were not recreated back into the original Cache folders.​​​​​​
      • Note: If none of the files are moved back into the original cache folders, the cache for other projects will need to be recreated which will slow down the initial time it takes to open the file.

An alternate approach, if you have access to a second system:

  1. On the second system, open Revit.
  2. Sign in to your own A360 account.
  3. Open the problematic model.
  4. Copy the newly created CollaborationCache files from the second system to the original system (overwriting).

If the method above does not work, then the more complete Alternate Sledgehammer Approach may help.

  1. With Revit closed, rename the CollaborationCache folder.
    • Note: This will force all model data to be re-cached. If the model can open, then it confirms that the locally cached copy was corrupt. If the issue persists, then the cloud model has become corrupt and will need to be rolled back to a previous version.
Preventative Care

For all Revit projects, Microsol Resources and Autodesk, inc recommended regularly open and audit your Revit model (daily, or weekly) to ensure that any damage or corruption is addressed as soon as possible. It is also important to address warnings to reduce the overall risk of model corruption. Please see our other blog, Revit Project Maintenance Guidelines. Consider taking a class with us, perhaps Revit Family Creation, Online
