ZWCAD 2009 has been relaesed, we recommend that you can download and install it, many features have been imporved and most previous problems have been solved includes the problem which you encountered. Thanks daia_silv 2009-01-13 08:39:24 http://www.zwsoft.com/forum/viewthread.php?tid=1243&pid=13030 I recently downloaded ZWCAD2010 trial version (installed standard). I edited some dwgs in it, and then saved as AutoCAD2004 format. But these drawings are not opening in AutoCAD2006. AutoCAD2006 hangs while trying to open these dwgs. What is the solution to this? Thank you. zw_admin 2010-11-09 10:03:18 http://www.zwsoft.com/forum/viewthread.php?tid=1243&pid=11174 I bought recently ZWCAD 2007 and I have a problem. After I made the drawing in ZWCAD I tryed to open with Autocad 2006 and 2007. It doesn't work. This should be autocad or zwcad problem? I mention that I install also ZWCAD 2008 last version but also without success. Thanks daia_silv 2009-01-09 18:03:10
