In a comment in response to my AutoCAD 2011 Help system is not popular post, Autodesk’s Diane Serda acknowledged the problems, offered apologies and posted a link to a CHM version of the Help. From Diane’s comment:
We have posted the zip file for download here: http://usa.autodesk.com/adsk/servlet/ps/dl/item?id=15068206&siteID=123112&linkID=9240618
1. Download the AutoCAD2011CHMHelp.zip to your local drive (such as My Documents\AutoCAD2011Help).
2. Extract the zip file to this same folder.
3. To access the CHM Help, you’ll need to click on acad181.chm or create a desktop shortcut.
You can also point to the locally installed HTML help by turning on the local help checkbox under Options, System. You can also access the PDF’s from the Online Help Home page under Online Resources. http://docs.autodesk.com/ACD/2011/ENU
Thanks, Diane! That saves people from having to do inconvenient and dodgy things like downloading a demo version of an AutoCAD 2011-based vertical (Civil 3D 2011 has CHM-based Help for the AutoCAD bits) and grabbing the CHM out of there.
Edit: when running under Windows 7 64-bit, the Search pane is blank, as it is in the CHM Help for earlier releases. That’s unfortunate, because searching is a major thing at which the browser-based system is currently very poor. The Index panel works, though, and it’s quick.
The PDF link is currently broken for me, but I expect it will be working before too long. In the meantime, the direct link to the list of available AutoCAD 2011 PDF documentation is http://docs.autodesk.com/ACD/2011/ENU/pdfs/PDF Documentation.html (beware, space in URL).
