Complete CAD File Repair Guide
Expert solutions for repairing corrupted CAD files including DWG, DXF, and design documents. Covers AutoCAD RECOVER command, AUDIT/PURGE workflows, and professional third-party recovery tools.
🛠️ Repair Capabilities
🔧 Corruption Types We Address
Drawing Database Corruption 📋 Internal database structures that store entity definitions, block references, and layer information. Critical for DWG/DGN files.
Entity & Object Damage 🎨 Corrupted geometric entities, blocks, hatches, dimensions, or text that cause display errors or crashes.
External Reference (XREF) Issues 🔗 Broken or corrupted external reference paths, nested XREF problems, and binding failures.
3D Model Corruption 🧊 Damaged mesh data, invalid solid geometry, or corrupted assembly constraints in 3D files.
Header & Version Issues 📝 File version mismatches, corrupted headers, or encryption problems preventing file opening.
⚡ Advanced Recovery Features
- Entity-Level Recovery - Extract individual objects from corrupted drawings
- Layer Reconstruction - Rebuild layer definitions and properties
- Block Recovery - Salvage block definitions and attributes
- XREF Repair - Fix broken external reference links
- Version Conversion - Downgrade files to recover in older software versions
🔍 Common CAD Corruption Signs
Warning Symptoms
- ❌ "Drawing file is not valid" error
- ❌ Application crashes when opening file
- ❌ Missing or corrupted drawing elements
- ❌ Unusual file size (too large or too small)
- ❌ Infinite loops during file opening
- ❌ "Recover drawing?" prompt on open
- ❌ Proxy objects or missing fonts warnings
- ❌ Exploded blocks or lost layer properties
Quick Diagnosis Steps
- Check backup files - Look for .bak, autosave (.sv$), or ~ prefixed files
- Try RECOVER command - AutoCAD's built-in repair before standard open
- Open in viewer - Use free DWG viewers to test file readability
- Check file size - Compare against expected size from recent backups
- Verify storage health - Check source drive for errors
