These tips will allow you to work more efficiently with the drawing files in AutoCAD for Mac.
Setting the default format for a drawing file can help when working in a mixed environment of AutoCAD users that are on different releases.
In AutoCAD for Microsoft Windows, there is a setting in the Options dialog box to set the default drawing file format that is used when using the SAVEAS command. The same setting is not in the Application Preferences dialog box on AutoCAD for Mac, but the setting can still be changed using the "DefaultFormatForSave" environment variable which is in AutoCAD for Microsoft Windows as well.
For example, the following sets the AutoCAD 2007/LT 2007 Drawing file format as the default format:
(setenv "DefaultFormatForSave" "36")
Change "36" in the example above example to one of the following based on the default format you want to use:
1 - AutoCAD R12 DXF
12 - AutoCAD 2000 DWG
13 - AutoCAD 2000 DXF
24 - AutoCAD 2004 DWG
25 - AutoCAD 2004 DXF
36 - AutoCAD 2007 DWG
37 - AutoCAD 2007 DXF
48 - AutoCAD 2010 DWG
49 - AutoCAD 2010 DXF
50 - AutoCAD 2010 DWT
