Hello,
I just saw that some objects I have in some documents are exported into a PDF in a different way I expected. I attach a simple circle.
As a PDF opening it in Adobe Illustrator, it is shown as "open path".
As an AI opening it there it is shown as "closed path".
Is there any hint in this objects that shows it could be understood as open path by illustrator in a PDF?
(I send some files often as AI or PDF to other creators or customers using Illustrator, so it's not about that I should not use or open it in Illustrator...)

What PDF setting are you using to publish your PDF in Draw?
I'll download your file and take a look, however you seem to have an easy solution simply send your Illustrator clients AI files.
I have never had a closed path in Draw publish to a print based setting PDF in Draw show up as an open path in ANY RIP.
If I remember this correctly waaay back when CorelDRAW was introducing PDF it was intended as an export filter for output not for editing in graphic applications. The same approach was taken earlier with the EPS filter. In my experiance Corel has never wavered from that approach from either filter.
A little information on PDF export only, X3 does not support transparency in spot color, X4 does, complex fills and live transparency was not supported until 2019.
Illustrator does not support opening PDF ffiles from CorelDRAW that support any high end complex fills and transparency.
yes, I could send an AI, but sometimes it's also better to send a PDF. I tested the prepress and the editing PDF option, both in RGB, but should be the same in CMYK and other PDF export options.
When I open it in Illustrator I see the curve is open, also when I open it in Infinity designer.
When I open the PDF in CorelDraw again, it's closed :).
So my question is less about any workflow or CorelDraw functionality or bug, more about what could be special about the circle in the attachment so that it is exported as an open curve as PDF while many other shapes I create or use are just exported fine as closed path?
But is "open path check" and "start/end node" something that PDF as a format understands? Is there any software that offers a preflight for the open paths? I did not find any. So perhaps if no editing is needed anymore and only printing (no cutting) this is perhaps ok after all.
I asked also in the Illustrator community and there I learned that it seems to happen as well when exporting from InDesign or Illustrator CC (when unchecking the Illustrator editing option, so deliver a final PDF). Then also the path is open the one node added.
But from CorelDraw I tried now all options, always it stays that way.
To solve this issue in CorelDraw it would be nice to change the editing PDF export option in that way that the path is not changed but still closed, just like the AI export option in CorelDraw. Actually the AI export option and the editing PDF export option should be similar that way.
Or is there any other hint how to maintain the closed paths of fillings in the PDF export in CorelDraw?
If you remember I mentioned Illustrator editing versions of PDF and EPS earlier.
I don't worry about the issue because I use PDF for output only.
If I send files to Illustrator I use the AI format because CorelDRAWdoes not support IllustratoreditingPDF and EPS. Better yet I avoid Adobe anything, Illustrator in particular.
BTW the AI file format I don't think has an output version only the native Illustrator editing.
Yes I will also deliver AI for more editing use.
For printing output of course PDF is needed mostly, and then it's now at least good to know that CorelDraw (as also Illustrator and InDesign) just opens all those paths and adds additional nodes :). So if a customer tells me he needs absolutely closed paths, then I can't export a PDF from CorelDraw. I could deliver a PDF from Illustrator though (with checkbox AI editing option), but then I just can deliver directly *.ai.
Still interesting that this was not known for CorelDraw and even not for the Adobe users as it seems (also did not find any discussion via Google).
It's far simpler than your thinking, if you're sending a file for output to a postscript RIP level 2 or 3 use a flattened PDF, if you're sending to a true PDF RIP you can send live transparency.
If you're sending a file that needs to be edited and it's not too complicated send your client an AI file with fonts set to curves.
If you're sending a file that is complicated for editing or for placing in InDesign simply do the file in Illustrator.
The reason for this is that a user working with InDesign may place Illustrator elements near your CorelDRAW elements, worse yet under or on top of your CorelDRAW elements.
Adobe and Corel handle complex fills, blends and transparency in different ways. This in many instances will cause errors, at least today with the advanced RIP's they will be caught int he RIP preview if the output professional has a true PDF RIP.
