Open the file into a binary viewer (TextPad, NotePad, etc). In the first line or two it should have a version level in it.

There is also a handy utility called "which version" or at least the executable is named which_version.exe. I don't remember where I got it, but the copyright on the file is by Didier Lacour, and the company name is "Ecole Centrale de Lyon". I have the French version, but I'm pretty sure there is an English version out there too.

I believe this is where I obtained the file, but don't see it attached here anymore.

Jim is right. Open CATIA file in a text editor and search the string MinimalVersionToRead . Its working no meter what OS are you using.

Just use this Perl code:
==================================
$/ = "\0";
while (<>) {
while (/([\040-\176\s]{4,})/g) {
$string = $1;
if($string =~ m#(\d+)/(\d+)/#){
$ver = $1;
$rel = $2;
printf "V%dR%d",$ver,$rel;
}
}
}
=====================================

Hi all,

Inquiring about information in regards to V5 R18 Vs. V5 R19? Information of differences between the releases? Or have there been any issues reported? Please let me know.........

The program directory is intended for any user who wishes to install or maintain the system, or access product data. The information is provided as an addition to the official documentation, which is available on your Documentation CD. The "General and Open Issues" section of the program directory includes any important or open issues you need to be aware of in a specific product. Also each workbench / product contains a section "What's New" that covers "New Functionalities", "Enhanced Functionality", and "Customizing Settings" that are new to each release. My first task with each new release is to review both of these locations for the workbenches I cover.
The V5 Documentation is one of the major improvmeents over the V4 suite. Please make use of this valuable resource! I hope that with V6 DS will start to include more Why to the V5 User Guides. This is one area that I fell could have been inproved.

Hi

Another way to check CATIA version of the part. If you have the part opened in Catia, just go to Desk and right click on it, then go to properties and you will see the version, release and service pack.

Thanks
