Troubleshooting: Drawing Corruption “I have more corrupt drawings in this release than ever before! Wh t iis A What AutoCAD t CAD d doing i tto my d drawings?” i ?”

ƒ

The Perception of Corruption

ƒ

Each new release improves the ability to detect corruption ƒ ƒ ƒ

Potentially more error messages because more corruption is being found Detection is product specific – not drawing specific Same drawings in 2010 product may report corruption not reported in 2008

ƒ

More frequent error messages may not mean more corruption ƒ It may mean better detection of existing corruption ƒ Corruption that was already there but was not previously detected
