How can I troubleshoot common CAD software issues | CADDEX India
Most Common CAD Errors & Quick Fixes
Problem: "Fatal Error" crashes in AutoCAD
Our 5-step solution:
- Type GRAPHICSCONFIG and disable hardware acceleration
- Delete the .tmp files in your Temp folder
- Reset AutoCAD settings with RESET command
- Install the latest AutoCAD hotfix from Autodesk
- Create a new Windows user profile if issues persist
Problem: Revit becomes extremely slow
What actually works:
- Purge unused elements (20+ times if needed)
- Disable "Drag elements on selection" in options
- Split large models into separate linked files
- Change visual style to "Hidden Line" when working
- Upgrade to SSD if using HDD (3-5x speed difference)

CADDEX Tip: We teach all students our "3-2-1 backup rule" - 3 copies, 2 media types, 1 offsite location. This prevents 95% of data loss cases.
Performance Boosters We Swear By
- AutoCAD: Set VTENABLE to 0 (disables smooth view transitions)
- Revit: Turn off "Show ambient shadows" in graphic display options
- SolidWorks: Disable "RealView Graphics" for complex assemblies
- All CAD: Add your project folder to antivirus exclusions
Indian PC Tip: Clean your CPU fans monthly - dust buildup causes 40% of overheating-related crashes in our climate.
When To Reinstall (And When Not To)
Reinstall if:
- Multiple files from different projects crash
- Error persists across different user profiles
- Basic commands like LINE or CIRCLE fail
Don't reinstall if:
- Only one specific file has issues
- Problems started after Windows update
- Other CAD software works fine
