AutoCAD is one of the most used CAD software around the globe. However, it is relatively expensive since it costs $1,575 a year. For interoperability purposes, Autodesk, the company behind AutoCAD and one of the largest names in the field of drafting and 3D CAD design, developed DXF (Drawing Exchange Format) to allow for interoperability between AutoCAD and other CAD programs. And you do not need to purchase AutoCAD to view a DXF file since there are several free DXF viewers available for download online that you can use to view DXF files without using a penny.
Use the AutoCAD web app to view or edit DWG drawing files online, or the web-based Autodesk Viewer to view DWG drawing files and other file types. Note: The editing capabilities of the AutoCAD web app are only available to customers who are subscribed to a desktop version of AutoCAD or AutoCAD LT. Anyone can use the AutoCAD web app to view files. Get a free DWG viewer to view, open, edit and convert.dwg files, the native file format for AutoCAD files. DWG Trueview includes DWG TrueConvert. DWG TrueView and other CAD file viewers See supported files and features, and choose the free CAD file viewer that's right for you. These are free-to-use for both personal users and companies. Need to view other file formats such as FBX, Inventor, or other files?
What are DXF files?
DXF (Drawing Exchange Format) file was developed by Autodesk and introduced in December 1982 to allow for interoperability of data files between AutoCAD and other CAD programs. The first AutoCAD version that was compatible with the DXF file format was AutoCAD 1.0.
The DXF was developed to provide an exact representation of the DWG file format, which is the native file format of AutoCAD. AutoCAD versions are lower than Release 10 only accepted ASCII forms of DXF files. However, higher versions support both binary and ASCII DXF forms.

Conclusion
Industrial designers’ and engineers’ work involves a lot of CAD files most of which are DXF files given the fact that AutoCAD is one of the most used CAD software. If an engineer or designer is working in a team where the teammates use AutoCAD, he/she will have to find a way of viewing, editing, commenting and sharing the CAD files from his/her colleagues. And to do so, he/she does not require to purchase the costly AutoCAD program.
He/she can simply download one of the above mentioned free DXF viewers for viewing, editing, commenting, and sharing the DXF files from colleagues.
