DWG is a file format used for storing design data. The .dwg file extension is used by CAD software like AutoCAD. Many CAD programs can open DWG files. You can view DWG files using free tools like Autodesk’s DWG TrueView. The DWG format efficiently stores 2D and 3D drawings. It is widely used for architectural and engineering designs. The format is proprietary and owned by Autodesk. But other software can open DWG files too. When you get a DWG file, first ensure it is complete. If downloading, try again if errors occur. Check you have permissions to open DWG files. Consider converting DWG to more common formats. This improves sharing with others lacking DWG software. Overall, DWG excels for technical drawings due to compression and CAD software support.
