The number and the relative dwg version: AC1015: DWG 2000 AC1018: DWG 2004 AC1021: DWG 2007 AC1024: DWG 2010 <img src="uploads/20110922_044752_dwgVersionNotep.jpg" border="0" /> magla 2011-09-22 04:48:17 http://www.zwsoft.com/forum/viewthread.php?tid=1790&pid=13518 ZWCAD 2011 How to get dwg version (2007,dxf,...) through VBA ? magla 2011-05-24 02:37:32
