For you to effectivily use ProductView Express, you will need to setup your config.pro file with the following options "save_drawing_picture_file" set this option to export and the second option is "save_model_display" set this option to shading_lod*. After completeing those 2 options you will need to resave any .drw, prt, or asm files that you want to view threw ProductView. Oh yea, for some reason if you want to view the drawing files you will need to open the .pic files.
