Free DWG Viewer
для Windows

Being one of the most common CAD file formats, DWG (Drawing) is a file format primarily used for storing and exchanging design and drafting data in the field of computer-aided design. Today, DWG files have become a standard for sharing and collaborating on design projects across various industries.

However, DWG is not as compatible as expected. In general, you can access and review DWG files with CAD software which always requires high system specification and takes up large storage. Luckily, some best free DWG viewers in the market are more lightweight to open, view, and modify DWG files with smooth performance.
