Below I've tried to open one of the sample drawings from AutoCAD 2008. The compatibility benchmark drawing BUDWEISER2008.DWG could not be opened at all for some reason.
After contacting ZWCAD Software I found out that ZWCAD could not provide the function to decrypt the files that have been encrypted. I removed the password from the drawing and tried again and found that there where some discrepancies. From what I could see in BUDWEISER2008.DWG there where at least 12 tests that failed.
Will Autodesk react on this and add some API support for AutoCAD LT?
