Is it possible to copy this bevel over to another edge? Okay, so I made this beveled detail here and I can't CTRL+Z to undo it. I have yet to save the file at all, can this bevel be copied over to the other corners somehow? or would it be better to revert it to the original shape somehow?
I think you should apply the mirror modifier on both the x and y axis. Then if you change anything on that edge it will apply to the others also.
