Drawing Interchange Format (DXF)

DXF (Drawing Interchange Format) was first introduced by AutoDesk AutoCAD, and is one of the most widely used CAD/CAM/CAE applications in the world. DXF is very popular and is supported by most 3D formats on PC platforms.

A DXF file is an ASCII file containing 2D and 3D components representing a drawing. Those components are known as Entities. The DXF file can represent almost any CAD drawing using those entities, and can connect a group of entities together (such as windows, doors, etc.) and use them later in the file. The DXF file has seen many changes through the years, from version 2.6 to the latest release version 14. However, the latest release of AutoCAD still manages to open files created with any of the earlier versions.

LEADTOOLS supports all current variations of the DXF format (versions 2.6, 9, 10, 11, 12, 13, 14).

Users can save a DXF file to any of file formats supported by LEADTOOLS.

The file constants associated with this file format are:

Constant	Write Support	Description
FILE_DXF	Yes	[58] AutoDesk AutoCAD ASCII format Release 12.
FILE_DXF_R12	Yes	Same as FILE_DXF
FILE_DXF_R13	Yes	[290] AutoDesk AutoCAD ASCII format Release 13.

When DXF files are rasterized, they are 24 BPP.
