Okay ... well there is a little triangle next to the create bar thinger. (I am tried so I will use words like thinger) Anyway you click on the little triangle and then you will get a whole selection of things like terrains and trees and such. You go to user items and as long as you have the item in question selected you should see it in the window. In user items you click on the add button and it will becoem it's own little item that you can use whenever you want .. that is the file you are talking about .. obd or whatever ..Good luck
