I don’t usually post if there’s an update available.
But I think this is a critical hotfix. I’ve seen several posts in CAD forums mentioning that people lost their entire drawings when they work in block editor.
The issue is AutoCAD will replace your drawing with the geometry inside your block. As long as I know, it happens when you work inside block editor and make a save (I guess it includes automatic save).
So if you’re using AutoCAD 2012, I strongly recommend you to download this hotfix immediately.

I tried and after the hotfix block editor doesn't work at all. i.e "command unknown"
The hotfix is supposed to fix saving problem when working with block editor.
Can you elaborate about the error? Did you also get the error message before you install the hotfix?
thank u its really usefull
