Thx for the answers. Didn’t work for me, event if i delete the object that is not the original, it delete the other to. The same goes by adding them in a new collection and delete the collection or the hierarchy. I would like to find a way to move out all the objects inside the object name ‘Floor’ in the picture.
UPDATE : Finally managed to do it. I unlinked the object ‘Floor’ (so the floor was deleted) and all the subs-objects was free again. It was messy because i moved some of them with the floor before so there were not at the right place but in the end, i just had to replace them and redo the floor. There is no more copies of all the objects and they are where they belong.
Thanks again for the help.
