About Importing and Exporting DXF Files

DXF and DXB files are two types of drawing interchange files used to transfer data between various applications.

A DXF (drawing interchange format) file is either a binary or an ASCII representation of a drawing file. It is often used to share drawing data between other CAD programs.

A DXB (drawing interchange binary) file is a specially coded binary version of a DXF file used for plotting, and can be used to “flatten” 3D wireframe drawings into 2D vectors.

You can convert a DXF or DXB file to DWG format by opening the file and saving it in DWG format. You can then work with the resulting drawing file as you would with any other drawing file.

You can export a drawing or (selected objects within a drawing) as a DXF file.

You can control floating-point precision of the DXF format up to 16 decimal places and save the drawing in either ASCII or binary format. ASCII format results in a text file that you can read and edit; binary format results in a significantly smaller file that is faster to work with.
