The same file is perfectly OK when opened (i.e. no warning messages) with 0.19
Any suggestions, please?

I had the same messages recently after changing from 0.19 to 0.20.

Check the dependency graph for red areas to locate the faulty parts. After I deleted these parts, the message disappeared. Strangely enough these errors did not occur in 0.19.

Thanks!
Unfortunately graphviz is failing to create images (in all FreeCAD versions, for all files) so I need to sort this out... before I have a look
Will be back

Some versions are known to not work properly with FreeCAD. You may try an older one. 2.36 works here well, but there are newer versions that work too.

I checked on another computer: 2.44.1 works too.

Thank you.
It was working fine on 0.19 previously, so it cannot (should not?) be related to Graphviz version?
It just stopped working, roughly about the same time I have installed official/latest 0.19.1 version.
Since then I have checked it on other versions of FreeCAD only to find that all have the same problem

So I don't know what it is

[bambuko]

OK, guys

Un-installed graphviz and re-installed it again (2.47.0 stable for win 10 x 64), pointed to it, and everything works fine.
So whatever it was (we will never know) the usual trick worked

Unfortunately I can't see any problems with dependency graph (attached) so we are back to square one - why warnings on 0.20 ?

OK, found a novel way of investigating issues with 0.19 created designs
Open them in RealThunder's Link Branch FreeCAD version and it gives you detailed report in the "Report View"

here what was wrong with my file:

Very easy to follow up and tidy up the detritus left by topo naming problems created while modifying the design.
But... why is this not reported by 0.19
Clearly 0.20 sees the problem also, but reporting is not detailed enough,
But... Link Branch not only sees the problem but reports details in most helpful way

If it wasn't for me openning this file in 0.20 and RealThunder's Link Branch I would be living dumb fat and happy, convinced that there is nothing wrong with it, because 0.19 wasn't complaining
