I’ve noticed a bug in AutoCAD 2008 that causes annotative text to disappear or become unselectable. This is very annoying, but there is a temporary fix.
Type AUDIT on the command line and then type Y to fix any errors it encounters. This will make the text selectable again – at least until you save the drawing. It seems this fix is very temporary and is not a permanent solution.
To address the problem with annotative text becoming unselectable when you save, set SAVEFIDELITY to 0.
If your annotative objects are not set with the drawing’s current annotative scale, they will disappear. Set ANNOALLVISIBLE to 1 to see ghost images of all annotative text in your drawing.
I turned these commands into a button macro to make it easy to check/fix a drawing with problems:
I hope Autodesk comes out with a permanent fix soon.
