Hello,
I am trying to groove a groove in the arc (see attached picture). I selected the arc face, created 2 datum points in the center of the arc and created datum line from them. Now when I try to groove around this datumline (support axis) the groove is weirdly deformed (see attached picture).
Is it a bug or am I doing it wrong?

Re: Grooving around datumline
Sketch001, Sketch002, and Sketch003 are all attached to generated geometry.
This has created a Topological Naming Problem (TNP) condition.
I think Pocket, Pocket001, and Pocket002 should be Pad, not Pocket operations.
Once these are corrected I think it will work correctly.

Re: Grooving around datumline
I have no idea how to make a pocket using a pad....
Re: Grooving around datumline
And the https://wiki.freecadweb.org/Topological_naming_problem describes a bug. And at the 7.) it describes a puzzle in Klingon language.

None the less, I see no Klingon problem in the link.
Here is your file with the TNP mitigation addressed and an example of less complicated approach.

Re: Grooving around datumline
Well, you are obviously a better soldier in this war of user-hostile FreeCAD, but that doesn't solve my problem for future projects. But thanks

Greetings to the Community!
you can also do this: just set the circumference to be subtracted from the center of the corner and operate with the subtractive sweep, indicating the external edges of the "T" as a path in succession

Re: Grooving around datumline
I don't get the user-hostile bit.
And, what does it not solve for future problems/projects?
For even more reference, your original approach with no dependency on generated geometry...as described in the links I've provided:

Sketch(000) is bad with T-vertex : impossible in PartDesign.
Should work symmetrical around YZ-plane
