FreeCAD is indeed smart enough to handle pockets correctly, whos Sketches are attached to faces. However, due to other reasons this is not recommended.

Maybe it is now - I'm running the repository head version and will test. I definitelty saw it being stupid this way in 0.18.4, I had to ask about it and was told about the "Reverse" checkbox, which indeed fixed the problem.

Please avoid terms such as 'stupid'. They unnecessarily charge the discussion. Everybody makes mistakes, but the word 'stupid' seldom applies.

I would like to see that example. Pockets of sketches attached to faces worked in 0.18 definitely the same sensible way as they do now: they go into the face (or rather into the material behind the face). Did you receive that recommendation here in the forum?

Someone has meanwhile marked the Spreadsheet Workbench page for translation and translated the added paragraph into French. That is a bit unfortunate as it is still a work in progress. I have now added the {{Page in progress}} template to discourage other translators from doing the same.

In your edit (https://wiki.freecadweb.org/index.php?t ... id=1033801) you say "You will get a warning and a request to confirm if a row or column deletion would abolish a reference that's used in your model." I am unable to reproduce that. In my test no warning is given. Can you provide a scenario where this warning does appear?
