Issue:
When opening or working on the file in Revit, either of the following messages are displayed:
Autodesk Revit is not responding
If you close the program, you might lose information
Not Responding
Revit eventually crashes after entering a "Not Responding" state.
Causes:
The file is too large compared to the amount of memory available.
Revit is not up to date.
Solution:
Please check the following to resolve the issue:
Check minimum system requirements
Make sure that the system meets the minimum requirements.
Update Revit
Ensure the latest Revit updates are installed.
Check storage disk sector size
The easiest way to verify whether disk sector size is causing the issue is to use Sector Info Checker for Autodesk® Revit®, see How to use Sector Info Checker Tool for Autodesk Revit. The tool runs without administrator permissions.

Check RAM size
To calculate the necessary amount of RAM for Revit to open a project, multiply the Revit project file size by 20 plus add 4 GB.
For example:
Project file, including linked files: 100 MB.
100 x 20 = 2 GB + 4 GB = 6 GB.
Adjust hardware acceleration settings
- Start Revit.
- Disable hardware acceleration.
- Restart Revit.
- Open Revit model.
Other checks
Disable any third-party plug-ins and retest: Check if add-ons are causing unexpected behavior in Revit.
The latest certified graphics card is installed.
Update Graphic drivers.
Update the BIOS and System drivers.
Links can be put into worksets and closed when opening. When opening only selected worksets and leaving others closed, performance improves.
- Open the linked model with Audit and perform Purge Unused Objects and reload it in the host model.
Note: This issue can also happen when saving a non-workshared Revit file to a network location. It may take longer than expected due to a backup being saved: About Backup Files for Network Saves.
