The DXF is primarily 2D-based and its format is a tagged data representation of all the information contained in an AutoCAD drawing file, which means that each data element in the file is preceded by an integer number that is called a group code indicating the type of following data element.

DWG (from drawing) is a proprietary [3] binary file format used for storing two- and three- dimensional design data and metadata.It is the native format for several CAD packages including DraftSight, AutoCAD, ZWCAD, IntelliCAD (and its variants), Caddie and Open Design Alliance compliant applications.
A 2D CAD drawing A 3D CAD model Computer-aided design ( CAD ) is the use of computers (or workstations ) to aid in the creation, modification, analysis, or optimization of a design . [ 1 ] : 3 This software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to ...
AutoCAD's native file formats are denoted either by a .dwg, .dwt, .dws, or .dxf filename extension. .dwg and, to a lesser extent, .dxf, have become de facto, if proprietary, standards for CAD data interoperability, particularly for 2D drawing exchange. [31] The primary file format for 2D and 3D drawing files created with AutoCAD is .dwg.
LibreCAD is a computer-aided design (CAD) application for 2D design. It is free and open-source, and available for Unix/Linux, macOS, and Windows operating systems.. Most of the interface and handle concepts are analogous to AutoCAD, making it easier to use for users with experience in this type of commercial CAD application.
These checkers can be built into specific CAD packages or work on a number of CAD file formats. In 2006/2007 Part 59 of STEP ISO 10303-59 Product data representation and exchange: Integrated generic resource: Quality of product shape data is under development. It defines how to represent quality criteria together with measurement requirements ...
As AutoCAD has become more powerful, supporting more complex object types, DXF has become less useful. Certain object types, including ACIS solids and regions, are not documented. Other object types, including AutoCAD 2006's dynamic blocks, and all of the objects specific to the vertical market versions of AutoCAD, are partially documented, but ...
