dwg is a proprietary file format used by the computer-aided design software AutoCAD and software based on AutoCAD to save design data. The DWG format and its ASCII format variant DXF have become the de facto file standard in CAD drawing data exchange, and it is estimated that there are more than one billion DWG files worldwide. Software that can open dwg format include: AutoCAD, DwgSee, Acme CAD Converter, ABViewer.

dwg is a proprietary file format used by AutoCAD to save design data. DWG files can be opened through autocad. Click [Editor] on the menu bar to edit the opened CAD drawing.
dwg, or DWG, is a proprietary file format used by the computer-aided design software AutoCAD and software based on AutoCAD to save design data, a set of Interact CAD software that started in the 1970s . Later, Autodesk obtained the copyright in 1982 and started using this file format. Autodesk owns, develops, and updates the DWG file format, and DWG is typically updated every few years as the company adds new features to AutoCAD.
The DWG format and its ASCII format variant DXF have become the de facto file standard in CAD drawing data exchange. It is estimated that there are more than one billion DWG files worldwide. Several companies are reverse engineering the DWG file format in an attempt to provide other design software with the ability to read and write DWG files. Autodesk also provides a set of DWG reading and writing technology development kit "RealDWG" that requires authorization.
The new version of AutoCAD can open many old versions of DWG files. AutoCAD 2007 can open version 2.0 DWG files and save them in the r14 format. In addition, Autodesk provides a free DWG viewing tool "DWG TrueView" for viewing all versions of DWG files. On the other hand, the company is a strong supporter of the vendor lock-in strategy, trying its best to protect the DWG file format and prohibiting the development of open source libraries that support the DWG format.

1. VOW Desktop
VOW Desktop is the most compact and lightweight permanent free DWG, DXF, DWF Picture viewing tools.
2.DwgSee
DwgSee Plus provides engineering design related personnel with access to AutoCAD DWG/DXF files (supported versions are R14, 2000, 2002, 2004, 2005, 2006, 2007, 2008, 2009, 2010) Tool software for fast printing and browsing without AutoCAD.
DwgSee Plus is a new type of DWG and graphic file management and browsing software with a small size and an Office 2007-like interface style, beautiful style and support for skin change. Comes with a commonly used font library to complete graphic file management and browsing. The built-in Dwg Viewer graphic browser implements ACDSee-like DWG/DXF file thumbnail preview effects; it supports management operations such as copying, pasting, cutting and deleting graphic files. It not only provides general functions such as graphic panning, full screen, and zoom, but also provides a unique dual-image synchronous browsing function, and supports full-screen mode, which is convenient for designers and reviewers to compare and view dual images. It is a must-have for engineering designers. Picture tool!
3. Acme CAD Converter
Acme CAD Converter is an excellent multi-functional CAD graphics tool software that can browse different versions of DWG and DXF files (R2.5-R2002), It can also batch convert CAD graphics files into GIF, JPEG, DXF, DWG, SVG, HPGL PDF and other formats, quickly output CAD graphics files into vector graphics, and save graphics files as high-precision bitmaps of any size for convenience. Processing in Photoshop and other software, supports full screen mode, supports the printout of color and monochrome graphics files and raster files, and can freely set the background color, supports the import of shx font files, xref block files, and raster files, supports Create associations to dwg and dxf files. Perfectly supports the display of Chinese fonts in CAD graphics.
4. Convert to .dxf file
The data structure of dwg files is a trade secret of Autodesk. Some professionals who deal with CAD graphics often hope to directly read and write dwg files. This method is more complicated to implement. The dwg file is in binary format and can be converted into a dxf text file through the converter in AutoCAD, which makes it easy to read and write data.
5.ABViewer graphics viewer
ABViewer is an ABViewer graphics viewer launched by Soft Gold. It is suitable for use at home and work. It can view, browse and edit CAD formats (DWG, DXF, HPGL, SVG, CGM, etc.) and about 30 raster image formats, the program can also precisely adjust graphics and convert them into different file formats. The program has batch processing capabilities.
ABViewer has an intuitive interface, and you can quickly find relevant options and commands on the toolbar. Files can be opened while browsing folders in the browser panel, and frequently used graphics are added to the favorites list.
