Hi, @ thomas-neemann and @manos, hello to the community!
I apologize for not having answered yet both to thank (for the appreciation @ thomas-neemann) and to give an answer in case of using sketch (@manos), I intend to return to the subject this week.
The reason for my non-response:
- while I was preparing the animated * .gif to show the steps (better "tricks") to do to align an "empty" Sketch on any plane, I found a serious error in the "Select floor" function, so I dedicated myself to reporting of this incorrect operation, here you can read it https://forum.freecad.org/viewtopic.php ... 2819af7043.
