When Calcs.com releases new features (such as new input toggles, updated load combinations, or logic improvements), these changes are automatically applied to new calculators. However, to protect your engineering work, existing projects are “version locked.”

​
Why are projects locked?

Usually, we will show you updates or prompt you to upgrade if there are changes in results that are critical, specifically if previous versions were found to be over-conservative or under-conservative. But if there are no critical safety implications, projects remain “version locked” by default. This is one additional layer to ensure that the calculations for a project you finished last month don’t suddenly change their results overnight just because a new feature was added to the platform. If you would like to use a new feature (like a new deflection toggle) in an older, existing project, you can manually force the project to upgrade to the latest version using the steps below.

​
How to force an update

To pull the latest calculation logic into an existing project:
1

Open the project

Open the specific project you want to update.
2

Navigate to Project Details

Navigate to the Project Details page (the main list where you see all your calculations).
3

Modify the URL

Look at your browser’s address bar. Add /upgrade to the very end of the URL.
Example: If your URL is https://app.calcs.com/project/effad11a-0389... Change it to: https://app.calcs.com/project/effad11a-0389.../upgrade

4

Load the upgrade page

Press Enter on your keyboard to load the hidden upgrade page.
5

Confirm & Select Calculations

You will see an upgrade confirmation screen like this, select the calculators you want to update.WHAT-APPEARS-AFTER-TO-ENTER.png
6

Export Previous Version and Upgrade

After selecting your calculators, a final window will appear. We recommend clicking Export and Upgrade so that you have a PDF record of the previous calculation version.AFTER-SCREEN.png
7

Compare Results and Utilization

Once the upgrade is complete, a Compare Results button will appear on the Project Details page.COMPARE-RESULTS.pngIf you click on it, you will see a comparison of the current and previous utilization checks. You should generally expect no increase in utilization, as an increase would mean the demand increased or the capacity decreased. We take the responsibility of our calculations very seriously, and scenarios like that rarely happen.UTILISATION-CHECKS.png

Important Considerations

Review your results: Forcing an update applies the newest calculation logic to all calculators within that project. While this gives you access to new features, it may also slightly alter results in other calculations if standard codes or assumptions have been updated since you created the project. Always review your critical outputs after an upgrade.
