Here is a summary of the responses, no great insights here except the Out of
Sequence variable set which I now remember from years ago.
When messing with trail files you want to set the environment variable
CONTINUE_FROM_OOS=true
With this set to true then Pro/Engineer will stop and sit when it encounters
an error in a trail file rather than dying without any warning or saving of
files.
If there are saves along the way, that can mess you up. I've had the most
luck where I've been working on a part without saving and it crashes. I'll
start a new session, save another part and exit - steal that chunk of the
the trail file and put it in place of the crash point of the existing file.
That way when I run the trail file, it will get to the end just before the
crash, save and exit. It's worked a hand full of times.
You have to weigh the benefits of recovering the work with just recreating
it. The trail file puts you to shame though because it can grind through 3
hours of work in 15 minutes
I always search for and delete segments before the last save. Obviously if
you try and work on the new part that got saved then your trail file might
try and reference something that has been changed. Also, I always save the
trail file as a training file then run in the training mode Vs trail mode.
That way if the trail file fails, the session of Pro/E does not crash, but
just stops at the failure point. This might allow some recovery. Another
consideration is start new sessions of pro on a regular basses, say lunch
time at the least. This will downsize the trail file and maximize recovery
possibilities. Not to mention, leaving a session of Pro/E running for days
starts to build up system issues where Pro/E does not always release memory,
regardless of having nothing in session.
For some strange reason, the default behavior of Pro/E is to crash if the
trail file goes out of sequence. You can set an environment variable called
CONTINUE_FROM_OOS to 1, and Pro/E will not crash, but just stop if something
is not right in the trail file.
If you're using Windows, you can add "set CONTINUE_FROM_OOS=1" in your Pro/E
startup .bat file, or add it to your Environment Variables (right-click My
Computer / Properties / Advanced).
Lots of good information in this thread. Thanks search forums feature.
