You know DWG DXF Converter support from AutoCAD 2002 to AutoCAD 2009. AutoCAD 2011 had released for some times. We start to transfer the software to AutoCAD 2010 and AutoCAD 2011. AutoCAD 2010 and AutoCAD 2011 are binary compatible. So after we successful compiled with ObjectARX 2010, the software will can run on both of them. We have finished most works, after a few days of testing; we will release DWG DXF Converter soon.
