Just happened that I deleted a surface by mistake, and it was not possible to bring it back with the classic undo (ctrl-z) option. It is NOT ACCEPTABLE that after so many versions and updates this option is not available on a software which is a standard for the industry and it has such expensive prices options. This is a basic feature that is available even on many other softwares, as someone already pointed out. Instead of focusing on adding minor program features, it would be much welcome to have what is necessary to work every day as professionals and not losing precious time.
Best regards
