Memory Usage and Performance

Learn strategies to improve Revit LT performance.

To minimize possible instability in Revit LT when its uses operating system memory, you can:

• Restart Revit LT regularly.

  If you receive a message that the current session's memory usage is approaching the operating system limit, save your work as soon as possible and restart Revit LT.

• Reduce the number of loaded DWG and RVT links. See Managing Links.
• Purge unused objects.
• Limit the number of views open. If you have multiple views open, you can quickly close all hidden views by selecting View tabWindows panel (Close Hidden).
• Use hardware acceleration when possible.
• Use optimized view navigation to improve performance when navigating views.

Note: In some cases, antivirus software solutions can lock files or slow data transfer, giving the appearance of memory limitations. See File Operations (Open, Save, Synchronize) Are Blocked or Slow for more information.
