Repair Revit Central Model: The Best Guide in 2023

How To repair Revit Central Model is one of the most asked questions in Google in 2022, in this blog post we will try to give the best answer with a step-by-step guide, common causes, preventives, and best practices.

Repair Revit Central Model

In the world of Building Information Modelling (BIM), Autodesk Revit is a leading software. It offers a feature known as the ‘Central Model’ for collaborative work. This shared file allows multiple users to work on the same project simultaneously. But what happens when the Central Model encounters issues? In this blog post, we’ll guide you through how to repair the Revit Central Model and ensure your team can continue collaborating effectively.

Understanding the Concept of Central Model

Before we dive into how to repair a Revit Central Model, it’s important to understand what it is. The Central Model is a Revit file that resides on a shared network location, accessible to all team members. When working on a project, each team member creates a local copy of the central file, works on it, and then synchronizes changes with the central model. This ensures everyone’s work is integrated, and the project stays up-to-date.

Common Causes of a Corrupted Revit Central Model

While working with Revit’s Central Model, you might occasionally encounter issues resulting in corruption of the central file. Recognizing the common causes of these problems can help you prevent them from occurring in the first place:

  1. Network Issues: Issues such as unstable internet connections, server timeouts, or network failures during synchronization can lead to corruption of the central model.
  2. Improper Shutdown: An improper shutdown of Revit during a synchronization process or due to a power outage can corrupt the central file.
  3. Software Bugs or Glitches: Although rare, software bugs in Revit can sometimes lead to central model corruption.
  4. Inconsistent Model Maintenance: Neglecting to maintain the model, such as not resolving warnings, not purging regularly, or not compacting the Revit files, can cause the central model to become overloaded and eventually corrupt.
  5. Overloaded Revit Model: Overloading the central model with unnecessary families, high-polygon elements, and large raster images can cause the model to become slow, unresponsive, and potentially corrupt.
  6. Working with Many Opened Views/Sheets: Synchronizing with many opened views or sheets might overwhelm the system, leading to file corruption.
  7. Uncoordinated Teamwork: In a shared model environment, uncoordinated changes made by team members can cause conflicts in the central model, leading to potential corruption.
  8. Unoptimized Revit Family Usage: Importing poorly optimized or excessively complex Revit families can have a detrimental impact on the performance of the central model, potentially leading to corruption.
  9. Incompatible Software Versions: Working with different versions of Revit within the same team can lead to compatibility issues, causing corruption of the central model.

Understanding these common causes can help you take appropriate preventive measures and minimize the risk of central model corruption. Regular maintenance, mindful modeling practices, and effective team coordination are critical to maintaining the integrity of your Revit Central Model.

Preventive Measures for Central Model Problems

Prevention is the cornerstone of smooth operations when dealing with a Revit Central Model. Adhering to Revit best practices can help you avoid the necessity to repair your Revit Central Model:

  1. Regular Updates and Cleaning: Ensure that all user stations are updated to the latest Revit build, and that users are regularly cleaning their TEMP folders.
  2. Wisely link CAD files in Revit – Ensure only necessary CAD files are linked to avoid overloading the model.
  3. Resolving warnings – Regularly check and resolve any warnings Revit gives you. This helps maintain the health of your central model.
  4. Use Revit worksets wisely – Keep your model organized by creating and managing worksets properly.
  5. Don’t overuse downloaded Revit families – Too many families can make your model heavy and slow down Revit. Use them sparingly and always check them before importing into your project.
  6. Print from detached files when working on large-scale projects – This practice helps keep your central model streamlined.
  7. Adequate RAM for Large Models: Working with large models with many links requires substantial RAM. Use the “Rule of 20”: a central file will need approximately 20 times its file size in available RAM.
  8. Manual Work-sharing Frequency and Coordinated Syncing: Change work-sharing frequency to manual, and avoid overlapping or concurrent syncing by users in multi-user work-shared Revit projects.
  9. Always purge your Revit model – Regularly remove unused elements to keep the file clean and lighter.
  10. Don’t over model, 2D elements are just fine – Avoid adding unnecessary detail to your model, especially when 2D elements can serve the same purpose.
  11. Don’t over-duplicate/create draft views – Maintain an organized view structure to avoid confusion and keep the model clean.
  12. Always compact your Revit files – This will help in reducing the file size and keep your model running smoothly.
  13. Compress your imported raster images – Large image files can slow down Revit. Compress them before importing to keep your model light.
  14. Always create a backup – This is your safety net if anything goes wrong with the central file.
  15. Regular System and Software Check: Verify hard wire connections, review server memory usage, ensure latest video card driver installation, Windows updates, sufficient free space on the computer, and control of storage drives that Revit accesses.
  16. Create a new central file every month – This helps avoid the accumulation of unwanted data and keeps the model fresh.
  17. Verify that CAD and RVT links are pinned – This ensures the linked files stay in place when changes are made.
  18. Save locally on a regular basis – Regular local saves ensure you don’t lose any work if issues occur.
  19. Don’t synchronize with many opened views/sheets – This could potentially overload the model and cause slow synchronization or crashes.
  20. Use a temporary view when making tests – Testing changes in temporary views avoids disrupting the central model.
  21. Don’t overload Revit with plugins – Use only essential plugins to keep Revit running smoothly.
  22. Use E-Transmit to send your Revit model – This Revit tool bundles all necessary associated files making it easier for model transmission.
  23. Avoiding Risky Operations: Avoid undoing after synchronizing, writing directly to a network path, using Wi-Fi connections, running multiple Revit sessions, and exploding imported CAD in an active project or a published family file.
  24. Regular Journal File Reviews: Check your journal files regularly for key words like “error, warning, crash, exception, fail & missing” to identify and resolve any potential issues
