Dwg Viewer Portable Top Now
Printing to PDF worked flawlessly. You can choose window, extents, or layout. The resulting PDF is vector-quality (not a blurry raster). Export to PNG gave me 300 DPI output by default – crisp enough for presentations.
Warning: The “Save as DXF” feature in the free version adds a small watermark “Created with DWG Viewer Portable Top” on the edge. To remove it, you need the paid Pro version ($29 one-time).
