Some statements in your posting are not fully correct. AutoCAD provides 3D functions since introduction of Mechanical Desktop back in 1996. Also importing 3D files and converting it in 2D has been possible in general, we did it here with AutoCAD 20 years ago. It is not correct, that AutoCAD cannot work with 3D or that only 2D was possible, that restriction applies only to AutoCAD LT, which is the (partly free) light version. DC-AE has also provided both 3D and 2D files of every variant through the CAD service and download website since 2007 and the ctrlX configurator seamlessly continues this, as stated in the comment before. For "non-ctrlX"-products 2D files can still be requested through the CAD service mailbox, while we look for a solution to make these available otherwise. If there is a corrupt file or a malfunction in ctrlX Configurator then please use the contact button inside to forward the case directly to the Configurator support team.
