Revit Tip: Optimizing Revit Project Files: Best Practices for Using the Purge Unused Feature


When working with Revit, one key aspect to maintaining an efficient and clean project file is to regularly optimize it by purging unused elements. This not only helps in reducing the file size, but it can also improve the software's performance. Let's delve into how to make the most of the 'Purge Unused' feature in Revit.

  • Regular Maintenance: Make a habit of purging unused elements regularly, especially before major submissions or sharing the model with others. This practice keeps the file lean and reduces unnecessary clutter that can slow down the model's performance.
  • Understand What Gets Purged: 'Purge Unused' removes elements that are not placed in the model, such as unused families, materials, or styles. However, it does not remove elements that are in use, even if they're not visible in the current view.
  • Check Dependencies: Before purging, Revit will show a list of items to be removed along with their dependencies. Review this list carefully to ensure that purging certain elements will not affect your design intent or the necessary components in your project.
  • Don't Forget to Audit: Combine the use of 'Purge Unused' with the 'Audit' feature. Auditing your project can fix errors in the database and can be done by clicking the 'Audit' checkbox when opening a Revit file. This step can further enhance project performance.
  • Save and Backup: Always save your model and create a backup before purging. In rare cases, purging can lead to unintended consequences; having a backup ensures you can revert to the previous state if needed.
  • Use Purge Unused for Views and Sheets: Remember that 'Purge Unused' can be applied not only to model elements but also to views, sheets, and groups that are not placed on sheets or used in model views.
  • Manage Shared Projects: In a shared project environment, communicate with your team before purging. This coordination ensures that items important to other team members are not inadvertently removed.

By effectively utilizing the 'Purge Unused' feature, you can maintain a more efficient Revit model, which is essential for collaboration, faster work, and ultimately delivering projects more successfully.
