save inventor file back to 2009

[jheisler]

i put a large amount of time into setting up a 2010 idw file in inventor. now a coworker needs to use it and the individual is using 2009. i have not found the usual capability to do a save as and drop the filetype box down to choose a previous version. is there hope of saving back to previous version, or has autodesk burned that bridge?

You have never been able to save back to a previous version in Inventor. Never have, never will.
