Common Issues and Troubleshooting

Despite its power, no software is perfect. Here are common AutoCAD 2021 issues and fixes:

• Problem: "Fatal Error: Unhandled Access Violation" on launch.
  • Fix: Reset the AutoCAD 2021 settings to default via the "Reset Settings to Default" tool in the Windows Start Menu.
• Problem: The Quick Measure tool shows "0.00" for everything.
  • Fix: Ensure that the OSNAP (Object Snap) is turned on (F3) and that you are not in a locked viewport.
• Problem: Drawing History says "No history available."
  • Fix: You must save the file to a cloud provider (OneDrive/Dropbox) or the Autodesk Docs folder. Local disk saving does not trigger history.
