Have you encountered a problem with a DWG file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a DWG file here. In the further part of this page we have added a list of programs that should open your DWG file. It is enough you choose a proper application for your operating system, download and install it.


The extension DWG derives from Drawing and is a file format of AutoDesk AutoCAD. It contains the design data for 2D or 3D drawings as well as metadata for their description.

AutoDesk changes this format from version to version of AutoCAD, so older versions can only handle the files to a limited extent. DWG is a proprietary and closed format that AutoDesk constantly seeks to protect.

With the help of the free AutoDesk DWG Viewer you can convert a DWG file into another version. This is useful because many programs can import DWG files but do not always support the latest version.

DWG is the quasi-standard for CAD (Computer Aided Design) files and is also used by IntelliCAD, PowerCAD, and other programs as the default format. The free Blender software can also read DWG files using Stani's Pythonscript Architects.

AutoDesk also provides a licensed library so that many programs can read the format. However, these z.T. Limitations.

As an alternative, dxf, IGES or STEP, either directly stored or converted there, are recommended as these formats are open and therefore better supported. However, the export or conversion may be subject to restrictions.

How to open a DWG file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the DWG file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a DWG file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support DWG files. At this point we are looking for disk space where the application was installed in and we can link it with a DWG file. Since then, our operating system will use the selected program to support all DWG files.

Other issues

Despite the described problem with DWG there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the DWG file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the DWG file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
