Trying DWG gateway

I just tried to install the free DWG gateway that enables you to save down a drawing from within AutoCAD : R14, R2000, R2000i, R2002, R2004, R2005 down to version 12 if needed. It can also open newer version of DWG files from older AutoCAD version. Of course you have to be aware that translations error can and will occur and maybe even corruption of the files.

Here are some drawings that I saved down to DWG version 12 and 13 from within AutoCAD 2005.
