When I open pre SW2009 files in SW2010 If I do a CTRL-Q rebuild, they have a tendency to crash.
Is this just me or are others having this problem?
What do you mean when you say the tend to crash? If you mean that SW crashes, then no, that isn't something I have seen, at least not very often. If you mean that features fail and you get cherries in your feature tree, then yes, that sometimes happens when you move to a new version. Almost all of our parts that have scultped types of faces have problems when we go to the next version. Simple prismatic types of parts usually don't have a problem.
Yes--as a general rule, if I open an assembly from, say, v2007--at least one of my parts will have some significant rebuild issues (though I use lots of surfacing-based features). So I've found the transition from v2007 to v2010 not to be terribly stable--but that's also a long gap.
I see similar things with my assemblies that have multiple configurations. In fact, some of those assemblies are permanently hosed (configuration switching will cause SW to hang and crash). So those configurations are gone. Deleting them and re-creating them produces mixed results, so the problem seems to reside in the older assembly file itself as opposed to the configurations. This is one that really kills me, since some of my projects are in mid-development and have lots of references among parts and assemblies. Starting the assembly over again from a new assembly file will kill all those references, which is a huge problem.
I always convert the in-house legacy files every version change and fix the very few that have problems ASAP.
The only time I open older version files is when they are downloaded from an external source (forums, vendors, clients, etc). Most of those open fine. The forum ones are often problematic, but that is to be expected because they are often problem files anyway.
