7 free DWG viewers

AutoCAD is one of the most widely used CAD applications around and AutoCAD files are everywhere from design to engineering including electrical engineering drawing. However, although AutoCAD is that versatile, it has a very high annual subscription fee. Therefore, if all you want to do is to view, modify, or even annotate DWG drawing files that are originally made using AutoCAD, you do not have to buy the costly AutoCAD application. There are lots of free DWG Viewers that you can download from the internet. 

And amazingly some of these free DWG viewer apps are made by Autodesk, which is the same company that develops AutoCAD.

DWG File Format

DWG, which stands for DraWinG, is the proprietary AutoCAD file format that contains all the metadata and geometrical data.

And due to its importance in design and engineering, DWG is supported by virtually all other third party CAD programs. 

In this post, Scan2CAD has selected the 7 best free DWG viewers that you can freely download to view and modify DWG drawing files.
