Can I recover a drawing if AutoCAD crashes before I hit save?

ByCADbrief Staff

Short Answer

Yes — in AutoCAD you can often recover a drawing after a crash by opening the automatic save file through RECOVER or by using drawing recovery Manager. This is the most common professional method because AutoCAD usually stores recent backup data automatically. However, anything created after the last autosave may be lost.

What You Need to Know Before

Warning: AutoCAD crash recovery only works if an autosave or recovery file was actually written before the crash. If autosave was disabled, the save interval was too long, or the temp folder was cleared, the drawing may not be recoverable.

How to Recover an Unsaved AutoCAD Drawing

  • Command: RECOVER

  • Shortcut: RECOVER

  • Quick Steps:

    1. Open AutoCAD, then go to the Application Menu (big A) and open Drawing Utilities > Recover, or type RECOVER.
    2. Browse to the autosave or drawing recovery file, typically in the folder set under automatic save file location, and select the latest .sv$ or damaged .dwg file.
    3. Let AutoCAD audit the file, then immediately use SAVEAS to save it as a new .dwg and verify the recovered content.

Variables & Settings

  • System Variable: SAVETIME (Default: 10)

  • Expert Setting: This controls the autosave interval in minutes. A shorter value reduces data loss after a crash, but setting it too low can slightly interrupt performance on large drawings.

Why it Fails

  • Cause 1 (Geometry): The drawing database may be corrupted during the crash, so the recovered file opens with missing objects or audit errors.
  • Cause 2 (layers/Locks): Critical objects may be on frozen, off, or locked layers after recovery, making it look like content is missing.
  • Cause 3 (Command/Logic): The crash may have occurred before AutoCAD completed the next autosave cycle, so the most recent edits were never written to the recovery file.

Quick Fix & Best Practice

  • Quick Fix: Use RECOVER on the newest autosave file, then run AUDIT and save the result with SAVEAS to a new DWG.
  • Manager’s Verdict: Recovery works well for crash events, but professionals should not rely on it as a primary workflow. Keep autosave active, reduce SAVETIME for active production work, and save manually at logical milestones.

FAQ

Where are AutoCAD autosave files stored?

They are usually stored in the folder defined in AutoCAD Options under the automatic save file location.

Can I open an SV$ file in AutoCAD?

Yes, rename the .sv$ file to .dwg or open it through recovery workflows if the file is valid.

Does AutoCAD always recover unsaved drawings after a crash?

No, recovery depends on whether AutoCAD created a valid autosave or recovery file before the crash.
