hello all - first time poster here (ie, noob)
forgive me if this is really easy question

i have a level that has lots of assets in it
unfortunately it was built in some random deep space world coords (including the ground)
is there a way that i can reset the entire level back to 0,0,0?

also what would have been the appropriate verbage to google this on?
the things i tried were way too general

tia for your knowledge and patience for this very basic question

Just go into top-down view, zoom out, select everything and drag it back to the origin.
