Yeah, it would be nice to have the ability to set Openoffice as the default spreadsheet reader for Inventor, but I don't know how to do that. Maybe someone at Autodesk does. Openoffice can read the spreadsheets from Inventor, but Inventor prefers Exel. On the good side, you won't need threads that often (and you could conceivably make the hole without them, get the file to another computer with Exel, and make threads there).
