Mini CAD Viewer is a simple tool for viewing DWG and DXF files.
Launch the program, navigate to the folder containing your files, and thumbnail previews will appear in the left hand pane. Double-clicking a file will display it in the main viewer, and zoom and pan tools help you take a closer look at any details.
Mini CAD Viewer also includes a Save tool, which allows you to save the document as a DWG file, or an image (BMP/ JPG), but that's about it.
The program is extremely basic. And there were a lot of our test DWG files that it couldn't open. It's simple enough to use, though, and should run on any PC from Windows NT upwards, so if you need a simple CAD viewer then it might be useful.
Please note, the program makes multiple attempts to install adware along with its own files. If that's not what you want, pay attention during setup and choose the various "Decline", "Cancel", "Skip" and other options as they appear.
