CADToPDF's PDF Output Appears "Corrupted" Internally

[apdc]

I'm not sure the best way to word this question.

Objectively, I would like to use CADImport's DWG->PDF functionality, and given the exported PDFs, perform some additional PDF operations on it.
However, it seems like the PDFs generated from CADImport might not truly conform to PDF standards or of some sort. While they appear to look fine in Adobe Reader. When I open the exported PDF in, for example Adobe Acrobat...I notice when I close the PDFs (that exported from CADImport), it prompts me to save my changes. Which leads me to believe, Adobe Acrobat has to rebuild the entire PDF when it opens it into the 'CADImport PDFs'.

I know it sounds a bit too techy, but I was wondering if there's any more details on the PDF settings of exported PDFs, or if there's properties to tweak to improve the export? Let me know if it you have any questions.

EDIT: I realized attachment PDF cannot be done here. But you can look at any PDFs that are generated from CAD Import .NET 8.

Hello.
PDF that generated by CAD Import .NET 8 not "corrupted" anyhow. Otherwise these files couldn't be imported by any Adobe software.
We have tested issue you described. It occurs if PDF generated with the library version 8.0 and doesn't with the version 8.1 (latest release). There is the change in the library 8.1 CADtoPDF class that affects metadata writing, like "Autor", etc in the created file.
We can recommend to download and try the latest library version. You can send a request to support@cadsofttools.com if you wish to receive the compatible library version.

Alexander.

Thank you for your reply! Yes, I couldn't think of the correct wording or best way to describe the issue at the time.

Thanks again!
