Hi Bernd,
It’s math I can do, so anyone can do it 🤣
As always in Blender there are many ways that lead to a result. At least now you have lots of options.
Btw. there are certain situations, where applying the rotation makes sense. I do this twice during the course I believe, but also explain why in that situation.
Under normal circumstances though mostly not the rotation and pretty much never ever the location. 🙂
Omar The “copy attributes menu” addon gets a specific mention in the beginning of the course. 😉
