As in title, here are my questions:
1) Current version is SW 2007. If I use SW 2009 to work with files created in SW 2007, and I saved it (gets converted to 2009), will I lose any details to my parts and assy, e.g., mates go wrong etc.? Any caveat I need to take note here?
2) Once files are converted to 2009 version, they cannot be accessed by SW 2007? True or False?
(P.S. if in wrong forum, kindly move thread.)
