What is the best way to export/save an image from the 3D window? I've tried switching on 2D antialiasing which helped somewhat, but when it comes to opening the file the quality is pretty bad. I've tried PDF at 600dpi on A1 sheet size without image compression, but didn't help much. Any tried and tested settings? Note that I don't want to save a 3D document view, place it on a sheet, etc. - I just want to remain lazy.
