I’m not sure that we all aren’t talking about the human appendix is some way. The PTC help file says you play the trail file in model player, and then I hear that you don’t do that. I guess someone is right in the issue, but it takes a long time to resolve all of the possibilities. Perhaps the trail file thingy isn’t used anymore, and the instructions have been allowed to lapse? This question was originally posted back in February.
I wanted to use the idea, since I lost an entire assembly in Wildfire 2 due to circular references or something. Even though many people tried to help, I never did recover the assembly, and have been worried should it happen again.
I received a couple of emails that explained how to get the suffixes on my trail files. What I have done is to go into Windows and Control Panel/Folder Options/File Types, and then select anything Pro/ENGINEER related. Using the “Advanced” button, I can check the box that says: “Always show extension”, and then I can see the trail.txt.x kind of mention. You really do have to do this before attempting to use a trail file to recover data.
Here are some other things I found out:
If I rename the trial file to “Copy of trail.txt” and delete the version, the icon changes to the one for a text file. The representational Pro/E icon disappears.
If I add the set_trail_single_step option to yes, no matter how I try to save that configuration to make it permanent, I have to either check or re-do that operation to get it to actually do what I want.
If I use Model Player to play the file, it plays rapidly through the steps and then exits Pro/E.
If I use a text editor to change the last few of lines in the “copy of trail.text.a” file from “yes” to “no”, the file plays rapidly and then stops without exiting. These lines are the record of my exiting Pro/E in the last session. Unless I make this change, the program exits. Duh!
If I use the trail_delay and set it to three seconds, the program ties up my 3.6 G computer screen so I really can’t use it for anything else. If I try to x-out the program to stop it, Windows says the program is not responding, even though I can see the model indexing through the commands. With the screen locked up, I can’t stop the model player at all, so were I to wish to stop the commands before my error, I couldn’t do it.
If I go into Windows, find the copy of trail.txt file and use Pro/E to open it, the file plays, but since I can’t find a way to save the config_pro file with the set_trail_single_step set to “yes”, it just plays through with no opportunity to stop the player before the error.
I don’t remember at the moment what I did to get the little screen with the ‘Single Step” command button, but when I did get that possibility, the Pro/E sash screen was extended, and I couldn’t see the model. The monitor screen wouldn’t respond and let me retract it.
I really do appreciate the folks like Eric Hill and Robert Pomarico and other people for taking the time to try to solve this. I just have the feeling that this trail file subject has changed from one edition of Pro/E to the next, and it’s being phased out by PTC. Who knows?
