How to delete file history saved with a model?

If you did a simple search for something like "File History Creo" you would likely come across the following article:

Article about File History 

In case you can't read such articles, the answer, regrettably, is a typical "Not part of Pro/ENGINEER, Creo Elements/Pro and Creo Parametric functionality".

That being said, if you do a "save as" and save the file to another file, the newly created file will not have all the file history stuff. It's tedious, but if you want to "replace" a file with one that doesn't have all the history, you could:

(1) Save As the file to another name within Creo.

(2) Close the file in Creo and remove it from memory.

(3) In Windows, rename the original file to something else, or delete it if you're feeling brave. Then rename the new file to the name of the old file.

Why do the renaming in Windows? Because if the part you are working with is in an assembly and you botch up the name flipping somewhere along the way your assembly will be a mess. Not something that is impossible to fix, but an annoyance to be avoided.

Lastly, I'm on Creo 4.0, so hopefully this "trick" works for whatever version of Creo you are using.
