AutoCAD 2020 PDFs cannot combine after creation

[Anonymous]

When PDFs are exported from AutoCAD 2020, those PDFs cannot be combined with any other PDFs (Using Adobe Acrobat DC). When attempting to do so, the application abruptly closes without warning or error message (have tested behavior on 3 different computers). This issue does not present with PDFs made from other sources, or other versions of AutoCAD. Have already attempted reinstallation of AutoCAD 2020.

No fix: Adobe needs to update, or you need to use a 3rd party PDF driver (or Adobe's own WIndows PDF driver).

That's unfortunate. Though it seems to me that if previous versions of AutoCAD aren't having this problem it should mean there is something AutoDesk COULD do about it, but is simply choosing not to.

It's unique to 2020 and may run into the just released 2021 versions too. AFAIK Autodesk doesn't seem inclined to address it yet or not enough Adobe users have complained enough here to warrant an update https://www.autodesk.com/company/contact-us/product-feedback
