  2. Download DWG FastView Portable and CADViewer. (Having two ensures compatibility if one fails to render a complex file).
  3. Extract the ZIP files directly to the USB drive (e.g., F:\PortableApps\DWGViewer).
  4. Add sample fonts (Copy *.shx fonts from your office to the USB drive to avoid missing font warnings).
  5. Create a "Start_Here.bat" file to auto-launch your preferred viewer.
