All versions of AutoCAD for Windows support the setting for default save as format, which is the format for modifying the defaults saved file in the OP settings for file interaction between different working environments. But AutoCAD2013 for Mac does not have this setting option, so that for a long time, every time to give someone to send a diagram, you need to use "Save as", and then choose the low version format, and then save, very inconvenient. So is there a quicker way to do it? Please see below PC6 Small series to bring you the solution.
Although the AutoCAD2013 for Mac does not modify the default Save Format dialog window, you can implement the modifications by entering commands. Copy this line of command to the AutoCAD command bar, and then enter, note: parentheses are required!
(setenv "Defaultformatforsave" "24")
Also, you can customize the two-digit number, and the different numbers correspond to the default save formats:
1-autocad R12 DXF
12-autocad-DWG
13-autocad-DXF
24-autocad 2004 DWG
25-autocad 2004 DXF
36-autocad DWG
37-autocad DXF
