tanks guys for the replay. I am modeling huge building architecture, windows, doors, bricks. glass, bla bla,,,,,
I did mistakes , I delete the history of the object, now i have trouble to rotate them as default way, it is centered to the object but not align to the object, it is bite hard to rotate/scale the object , I tried every way, but didn't change at all, also I cant get back to the step one, I cant model all the stuff again.
so i am in bite hard situation.
hit D and move the pivot to the corner or center of the object and than scale it,(it is helps) but I have nearly 2000
object(city) in my scene, so I can not go through every single object and center the pivot to the edge or corner of the object to scale it,
that must be some other way,
remember the history has been deleted,
