AutoCAD® DXF Format

The Drawing Interchange Format (DXF) enables the interchange of drawings between AutoCAD and other programs. DXF files can be either ASCII or binary formats.

LinkCAD is compatible with all versions of the DXF format and has full support for REGION entities.

File Structure

Essentially a DXF file is composed of pairs of codes and associated values. The codes, known as group codes, indicate the type of value that follows. Using these group code and value pairs, a DXF file is organized into sections, which are composed of records, which in turn are composed of a group code and a data item. Each group code and value are on their own line in the DXF file.
