If you're one company and everyone is on the same page, that works fine.
What if you're a consultant and you have customers running three
different versions? It means bloating your machine with three different
versions of Proe, dealing with compatibility and licensing issues
between versions on that machine, or maybe having a completely different
machine for each version, all costing money, time, aggravation, etc.
Sure, it can be dealt with, because we have to deal with it, but
everyone I deal with isn't going to upgrade just because I don't have
their version, or they don't have mine. You have to realize that
maintenance and upgrades with PTC don't come cheap, and forcing a
customer to upgrade, or forcing me to upgrade, is not a light decision.
It is much simpler to be able to open and work with a file that is one
or two versions ahead, or behind, of your own. Just two versions back
would be enough. It would mean the upgrade decision could be based
purely on functionality and benefit to you as a company, rather than
being forced to deal with something because PTC wants more money from
you. I have to give PTC credit for the ability to open WF3 files in
WF2. That is much needed, and that functionality is used. Will they
continue to offer that in later versions, like WF4 and WF5? I hope so.
