Another PDF export assembly

I have downloaded every piece of code I can find, and nothing seems to do what I need. We work in assemblies with a top assmebly and then a bunch of sub assemblies below it. Most files have a print or set of prints in it. Some do not have a print though.

Top Assembly-
//-Cavity Assembly
////-Cover Cavity
//////-bolt
//////-bolt
//////-bolt
////-Ejector Cavity
//////-bolt

There are a lot of repetitive part files in our assemblies. Some of these parts are standard pieces that we keep on a shelf. To keep from recreating them over and over, we keep them in a directory and pull them out into our working directory as needed. These all have their drawings inside their own files. This keeps us from redrawing prints also. We are required to have the title block info that matches what we are working on. This is pulled from expressions in a "titleblock" file in the same directory. It works and keeps us from doing a lot of repetitive work.

Upon finishing a design, we have the "top assembly" open with all title block info updated. It would be nice to be able to do File->Export->PDF->"All Open Part Files With Drawings". That will never happen. I would also like it to put all of the prints into one PDF file.

I tried the export all in a directory journal code, but it calls the first file up and then errors with "part file already exists".

I tried one that was supposed to export all in an open assembly. It repeatedly made a lot of the same files displayed part, because we have a lot of the same components over and over.

Am I missing something that is already out there, or is this something I will have to create? I am not a programmer, so it is all way over my head, but if someone can point me in the right direction, I will give it a try.

We currently run NX9. No Teamcenter.

Thanks,
