http://www.zwsoft.com/forum/viewthread.php?tid=2248 When trying to import profile (.arg file) from ZWCAD2011 to ZWCAD+ 2012 I get the message: "the profile file selected is not a valid REGEDIT 4 file format, canceling command". So, how do I do that? Many thanks marin Marin 2012-07-08 03:37:39 http://www.zwsoft.com/forum/viewthread.php?tid=2248&pid=15334 Hi, if you compare the arg file exported from ZWCAD 2011 and ZWCAD+, you will find it very different, because ZWCAD+ has changed a lot from bottom up, especially with a new Ribbon interface. So currently there is no way to import an old version arg file into ZWCAD+. huangy8949 2012-07-09 09:48:01
