I might be a bit thick so bear with me but I cant find a “ReDo” button to go along with the “UnDo” I regularly come back to a drawing hours after starting do something wrong… hit undo nothing happens hit undo, repeat loop several times only to find u cant undo (in this case a move of the part on the bed) now i have no idea what the 5 or 6 undo’s were! And I cant redo them?
Or can i?

I am sorry but there isn’t any redo at the moment. Undo doesn’t currently store enough information to redo.
