The technology preview of Factory Layout Optimization for AutoCAD was launched with great fanfare at Autodesk University. As such many people are trying it. You can try it for yourself.
At this time the technology preview only supports English versions of AutoCAD 2011, AutoCAD Architecture 2011, and AutoCAD Mechanical 2011. Based on your initial feedback, the team is expanding the list of supported languages. Of course this means more to test and will take time, but they are on it.
To all non-English AutoCAD, AutoCAD Architecture, and AutoCAD Mechnical users, we thank you for your patience while we make this update.
Expanding the preview to get even more feedback is alive in the lab.
