The AutoCAD 14.01 update included some minor modifications to the DWG file. It has come to our attention that some other CAD packages (specifically those based on certain libraries which attempt to reverse engineer our drawing file format) are having difficulty reading files saved using the AutoCAD 14.01 update. This patch alters the 14.01 DWG-write algorithm so that it saves its files in a manner recognized by these other CAD systems. Neither 14.01 nor this patch have any impact on DWG compatibility in an AutoCAD Release 14 environment. Only AutoCAD customers who exchange DWG files with other CAD packages may need to download the patch.
**"Unlocked version" refers to single-user AutoCAD software that does not ship with a hardware dongle (lock).
NOTE: This patch will not update AutoCAD Release 14.0.
