Ive been messing arounf on radiant and made this Building, (i know it CRAPP) but im learning how to cut windwos/Doors.
Due to the building is very big, how do i make it small enought to fit into my map as a standard building. And do i save as a Xmodle or a Prefab. What ever way i dont know how to save it, can someone point me the right direction.

Cheers.
