My client sent me a DXF file  and I can't open it on my Windows 11 PC. I am not a CAD expert, so I am not sure whether the file is damaged, whether Windows needs a special viewer, or whether I need full CAD software just to view the drawing. I only need to open and check the DXF file, not do advanced editing. A lightweight and beginner-friendly viewer would be ideal, especially if it can zoom, measure, print, and display layers correctly. What is the best DXF file viewer available for Windows 11 right now? Are there any reliable free tools or official CAD viewers that work well with DXF files? Thank you.
