Drawing (DWG) files are the native data files that are created when using AutoCAD-based products.
Each AutoCAD-based product uses a specific file format when saving to a file, which is important when sharing files with clients and other users in your company.
The following table outlines which file format should be used when sharing files with other users of AutoCAD or AutoCAD-based products.
| File Format | AutoCAD Release |
|---|---|
| AutoCAD 2013 | AutoCAD 2013 through AutoCAD 2016 |
| AutoCAD 2010 | AutoCAD 2010 through AutoCAD 2012 |
| AutoCAD 2007 | AutoCAD 2007 through AutoCAD 2009 |
| AutoCAD 2004 | AutoCAD 2004 through AutoCAD 2006 |
| AutoCAD 2000 | AutoCAD 2000 through AutoCAD 2002 |
| AutoCAD R14 | AutoCAD R14 |
| AutoCAD R12 DXF | AutoCAD R13 |
| AutoCAD R12 DXF | AutoCAD R12 |
When working in an office that uses multiple AutoCAD-based product releases, you can set the default file format to use when saving to a file.
