TRAIL FILES questions

Hello ProE users...

My question has to do with the trail.txt file generated after every work session in proe.

Why is this file genrated?

How can it be used?

Is it possible to prevent it being generated?

Is it possible to delete all previous trail files generated so far as when old versions of a part are deleted?

thanks, regards

Al.

TRAIL FILES questions

FWIW, I have a VB Script that runs each time Pro/I is launched to clean
out all trail files more than 14 days old (so they won't accumulate
unchecked). Apparently you aren't familiar with the functionality to
replay a Trail file in Pro/E; look into it, it could come in handy some
day.

TRAIL FILES questions

On the subject of trail files, I have very little luck getting them to work
without crashing. I can have a trail file that at the end of the session
pro-e has crashed, so I remove the last section(s) of the trail file to
remove the hic-up that caused the crash. But more often than not when I play
the trail file it will hum along for a while, then crash pro before it even
gets to the end of the trail file. Is there a special way to edit parts out
of the trail file? Is there a special way to end a trail file? How do you
decide how much to remove?



Any enlightenment would be much appreciated!

TRAIL FILES questions

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 🙂

TRAIL FILES questions

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).

TRAIL FILES questions

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.

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.
