Does anyone here use Inventor 10? If is so What type of files can you open with it? We have Inventor 11 here but I need to get the file out to a inventor 10 format. I know you can not go back only forward. I have sent this customer many type of different files which they are all having trouble to open. I would like to see if someone here would be interested and trying to open one of these files I am trying to send out. Thanks
