Can pro-e open granite files and neutral files that were saved by inventor? Also can they be modified as if they were started as a .prt or will they be like a .sat file that limits the amount of modifying that can be done? The exchange would be between IV 2009 to pro-e wf3. I need to open up granite files from Inventorand be able to change anything on that part as if I started it. Can this be done?
