How to arrange things on the shelves? (Fallout 3)

1. what the fuck are you deleting a topic? but?
2. in general, I need help - I would like to know how to put all things on the shelves in cabinets (not inside, but in open boxes) on tables, etc ... downloaded, for example, a mod with a house for Megaton (room is added) and there in the box neatly lie 2x 10mm pestles + 2x Laser pestles + a Chinese sword on the shelf above =)) and
so this is the question - I have things weighing 1500 kg, and I will arrange it for a long time (you know) ... program or through which you can put everything on the shelves? should i throw everything out of inventory? please tell me, I beg you ...
