遇到AutoCAD文件損壞時(shí)，可采取以下步驟嘗試恢復(fù)：1. 檢查自動(dòng)備份文件，查看原始.dwg文件所在文件夾是否有.bak或.sv$文件，并將.bak文件重命名為.dwg以打開(kāi)；2. 使用RECOVER命令嘗試修復(fù)文件，若失敗則使用-OPEN命令打開(kāi)文件進(jìn)行部分恢復(fù)；3. 采用第三方工具如DataNumen DWG Repair、Recovery Toolbox for DWG等處理嚴(yán)重?fù)p壞的文件。為預(yù)防未來(lái)?yè)p壞，應(yīng)定期保存并使用“另存為”刷新文件結(jié)構(gòu)，保持軟件更新，避免通過(guò)網(wǎng)絡(luò)驅(qū)動(dòng)器保存，啟用自動(dòng)保存并設(shè)置較短間隔，以及定期使用AUDIT命令檢查問(wèn)題。

Sometimes AutoCAD files get corrupted, and when that happens, it can be stressful—especially if you're on a deadline. The good news is, there are several methods that often help recover your work without losing too much progress.

Check the Automatic Backup Files

AutoCAD has a built-in feature that creates backup (.bak) and automatic save (.sv$) files. These aren’t enabled by default in every setup, but many users or companies configure them for added protection.

• Look in the same folder where your original .dwg file was saved
• You might see a file with the same name but ending in .bak or .sv$
• Rename the .bak file to .dwg, and it should open normally in AutoCAD
• If you find an .sv$ file, check the "Autosave" location in AutoCAD under Options > Files > Automatic Save File Location

This doesn't always give you the most recent version, but it's usually better than nothing.

Use the RECOVER Command

AutoCAD includes a recovery tool called RECOVER. It’s not perfect, but it's one of the first things to try when a file won't open properly.

• Type RECOVER in the command line and press Enter
• Select the corrupted file
• Let the program scan and attempt to fix issues
• Sometimes layers or objects may be missing afterward, so double-check everything

If RECOVER fails, you can also try opening the file using the -OPEN command (with a dash), which bypasses some startup routines and sometimes lets you access the file enough to salvage parts of it.

Try Third-Party Recovery Tools

If the built-in tools don't work, there are third-party programs designed specifically for recovering corrupted DWG files. Some are free, while others cost money, but they can offer more advanced scanning and repair options.

Popular ones include:

• DataNumen DWG Repair – Often recommended for serious corruption cases
• Recovery Toolbox for DWG – Simple interface, works well for moderately damaged files
• CNC Software DWG Recovery – Another solid option, especially for older DWG versions

Make sure to download these from official or trusted sources to avoid malware. Also, keep in mind that success depends on how badly the file is damaged.

Prevent Future Corruption

Prevention isn’t foolproof, but it helps reduce the risk. Here are a few habits that make a difference:

• Save frequently and use “Save As” occasionally to refresh the file structure
• Keep your AutoCAD software updated
• Avoid saving over network drives whenever possible; local saves are more stable
• Enable autosave and set it to a short interval (like every 10 minutes)
• Regularly audit your drawings using the AUDIT command to catch small issues before they become big

Basic precautions like these go a long way in avoiding future headaches.

基本上就這些。 Recovering a corrupted AutoCAD file takes a bit of patience and knowing where to look. Start with the easiest options like RECOVER and backup files, and move to more advanced tools only if needed.
