Extruded circles, donuts, and rectangle objects export as AutoCAD circles,
donuts, and trace objects with a thickness property.
AutoCAD Interchange (DXF) Files
Importing DXF Files
File menu > Import > Select File To Import dialog > Files Of Type > AutoCAD
(*.DXF)
If using a DWG file is not an option, the DXF file format is the next best
method of getting design data to and from 3ds Max. Most commonly, DXF
files are used to import and export modeling data to and from CAD programs
that have support for DXF but not DWG files.
When you import an DXF file, the software converts a subset of AutoCAD
objects to corresponding 3ds Max objects. Importing DXF files employs the
same methods as importing DWG files. For more information, see
Importing
AutoCAD Drawing Files
on page 6979 .
Exporting to DXF Files
File menu > Export > Select File To Export dialog > Save As Type > AutoCAD
(*.DXF)
DXF files are used to import and export objects to and from AutoCAD (and
other programs that support this file format).
NOTE The DXF Exporter can export only mesh data. Therefore, all shapes and
splines
on page 7929 are exported as mesh objects. Consequently, any open splines
(which cannot be converted to mesh objects) in your scene will not be exported.
