Why am I getting an error -27 when opening a dwg file
Current version of DWG Viewer (1.6.6) supports up to autocad 2009 format. The file being opened is created by later version of auto cad (2010/2011 format). We are currently working on 2010/2011 format. The solution in the meantime is to re-save the file from auto cad as 2009 format.
Why do I get error -27 when attempting to read DWG file ?
Attempt is being made to open a dwg file format that is not currently supported in DWG Viewer. Version 1.6.6 support dwg 2007/2008/2009 (AC1021) format. Version 1.7 supports dwg 2010/2011/2012 (AC1024) format.
