What are .DWG files?
A DWG file is a format for storing 2-D and 3-D drawings, data, and metadata. The format contains binary codes instead of pixels, which are scalable endlessly while preserving image quality. A DWG file stores highly compressed data.
DWG format means 'Drawing,' which can be identified using the .DWG file extension. The format is a vector file with all the data required to describe the designed objects' metadata, annotations, dimensions, and shapes.
A DWG file stores each angle, measurement, and other relevant data regarding the design for easy sharing and editing using CAD software. A .DWG file extension is an AutoCAD drawing that can be used with CAD programs.
The DGW files are related to various other file types including:
- .SV$
- .DWS
- .DWT
- .BAK
DWG file format is unique and standout from other vector graphics formats such as SVG because:
- Backward Compatibility: The oldest DWG files can run on the most advanced AutoCAD versions, allowing users to easily access old legacy designs and project work when the software is updated. Note: legacy Autodesk software versions may not read DWG files created with newer software.
- Proprietary Format: Unlike open-source file formats DWF and DXF, the DWG file type is proprietary. As such, DWG files are only supported and compatible with Autodesk. Many CD programs can open and edit DWG files, although not all fully support all features.
- Smaller Files: DWG files are detailed and hold more data. Since the format only stores binary code information, its files are compact compared to other CAD formats, such as DXF. Thus, DWG files are easily handled on email and cloud-based platforms like Outlook and Google Drive.
History of DWG image Files
Autodesk licensed the DWG file format in 1982. However, Mike Riddle and his team developed a blueprint in 1970 that became the foundation for the AutoCAD file format. The format is exclusive to the CAD software but has evolved to include more features like DWGCHECK and TrustedDWG.
The DWG format was created with AutoCAD software to allow industrial experts, including architects, designers, town planners, and others in the same professions, to visualize ideas and concepts easily in multi-layered designs.
DWG files contain user-generated information like maps, photos, geometric data, and designs, increasing their adoption by designers, engineers, and architects for different design purposes. The global market has various CAD programs, making the DWG file format open and accessible to ordinary users.
What are DWG files used for?
The DWG file format is used to create and store detailed design data in fields like engineering, architecture, and city planning. These files contain complex layers, including comprehensive technical specifications, diagrams, and 2D and 3D drawings.
DWG files also store metadata and vector image data. The metadata helps manage design information, while the vector-based images enable accurate representations of 2D and 3D concepts on screen.
Pros and Cons of DWG files
The DWG file format benefits architects, designers, and engineers by helping them create and produce expert digital drawings or drafts used globally. Nonetheless, while the format is used to create 2D and 3D drawings such as product sketches, floor plans, etc., it has some demerits.
Advantages of DWG files
- High-Quality Images: DWG files preserve all image details and can be scaled up or down without losing resolution levels.
- Real-World Working Environment: DWG files can be used to test design plans and create prototypes for real-world contexts, including inspecting objects' sizes, locations, and positions.
- Economical: DWG files store all details together, enabling users to design, save, and edit their blueprints in one place.
- 2D and 3D Image Manipulation: DWG files are supported by 3D and 2D images, allowing engineers and designers to produce versions of each in one File, hastening the review and feedback process.
- Smaller File Sizes: DWG files consist of binary codes, making them smaller and ideal for storing and exchanging data between different CAD programs.
Disadvantages of DWG files
- Specialized Software: DWG files are a proprietary format for use with the AutoCAD program. While most software opens them, some features are invisible without CAD software, limiting their sharing across platforms.
- Limited Support and Capability: DWG file formats are prone to compatibility issues when users have different CAD versions.
- Versioning: DWG file format and AutoCAD have evolved, integrating new features, which make older versions of the AutoCAD program incompatible with the added features.

4 Can you print DWG files?
Yes, you can print DWG files using AutoCAD TrueView or DWG TrueView software, which displays and prints any AutoCAD file.
5 What is the difference between DWG and DXF?
A DXF file is an open standard format designed for compatibility between various CAD programs, whereas a DWG file is Autodesk's proprietary native format. Both file types can be edited and opened in Autodesk programs.
6 What is the difference between a DWG file and a DNG file?
A DWG file is the proprietary format for CAD programs like AutoCAD, developed by Autodesk. In contrast, a DGN file is the native format for MicroStation, a Bentley Systems 2D and 3D modeling program.
7 What is the difference between DWG and DWT?
A DWG file is a standard AutoCAD drawing file containing design data for 2D and 3D drawings. In contrast, a DWT file is a template used in AutoCAD. A DWT file contains predefined settings, such as layers, line types, and dimension styles, which create new drawings with consistent formatting. While the DWT file is used as a template, new drawings created from it are saved in the DWG format for further use in CAD software like AutoCAD.
