The Archive Bin is an object you can add to your map in DEdit. Open the TRON.DEP project > Create a new World > Click the right mouse button > Add > Object > ArchiveBin > click OK.
But for other things, like terminals . . . yeah. That's a bit of a problem. BVG gave us almost no prefabs, which are pre-made geometry objects from the game. Basically, in most cases, you are stuck having to create them yourself.
But if you load the sample maps that came with the editing tools, you can sometimes take things from those maps and put them in your own by copying and pasting.
