What is a DWG file?

open dwg fileA DWG file is a database of 2D or 3D drawings that are generated with AutoCAD, which is a professional CAD program. It consists of vector image data and metadata that describes the contents of the file. DWG files are associated with the .DXF files, which are ASCII versions of DWG files. A file having the.DWG file extension is an AutoCAD Drawing Database file. It saves the metadata and 2D or 3D vector image drawings that can be used with the CAD programs.DWG files are compatible with lots of 3D drawings and CAD programs, which makes it very simple to transfer the drawings between programs. However, as there are several versions of the file format, some DWG viewers can not open every type of DWG file. DWG (drawing) is an AutoCAD (Computer-Aided Design) file format that is used for saving two or three-dimensional design data and metadata. 


It is one of the most commonly used design data formats, which is also supported by IntelliCAD and all its variants, PowerCAD, and several other software applications. At the same time, Autodesk has not been able to attain a trademark for DWG. In 2011 the USPTO issued a final refusal to register DWG as a trademark owned by Autodesk’ later in 2013 it affirmed this decision. The struggle between Autodesk and OpenDWG Alliance proves the popularity and helpfulness of DWG as an image file format.

  • Zamzar can convert DWG to PDF, JPG, PNG, and other similar file formats. As it is an online DWG converter, it is much faster to use than one that you have to install into your computer. However, it’s only the best option if the file isn’t too large since anything really big will take a long time to upload/download.
  • Other DWG files can be converted with the DWG viewers, For example, the free DWG TrueView program can convert DWG to PDF, DWF, and DWFX, DWS, and DWT for free. The latest versions of DWG file formats can not be opened in older versions of AutoCAD. See Autodesk’s instructions on storing a DWG file to an earlier version, like 2000, 2004, 2007, 2010, or 2013. You can do it with the help of a free DWG TrueView program through the DWG Convert button.
  • Microsoft has commands on using a DWG file with the MS Visio. Once opened in Visio, the DWG file can be converted to Visio shapes. You can also store the Visio diagrams into the DWG file format. AutoCAD should be able to convert the DWG file to other formats like STL (Stereolithography), DGN (MicroStation Design), and STEP (STEP 3D Model). However, you might get a better conversion to the DGN format if you use the MicroStation software to import the DWG file.
