I wonder how an older version of excel will handle opening an excel
2007 file that has data in extra columns that it now has. Excel now is limited to like 256 columns...Excel 2007 is suppoosed to increase that to around 1600. Will it strip it off with a warning? Or just fail to open that file?
I'd think that the best we might see in the future is possibly just the option to save it back to an older version but with no features. Kind of like exporting a parasolid, then reimporting, just fewer steps.
I don't think people realize the programming effort this requires. Imagine all the things a save back function would have to check for. Features that didn't exist, options on existing features that didn't exist, etc.
I think a save back option would be way less than perfect, and be such a headache to users that they wouldn't bother with it. Solidworks would be bombarded with calls about how it doesn't work.
Hell, I get errors on models that get converted to the new version...imagine the nightmare of it saving back.
