Best way to multi duplicate?

Hi,

I am modeling a warehouse. The room is a very basic, lowpoly cube with some textures. I have also done a shelf and a box. These are also pretty basic stuff. My plan is to duplicate the box, maybe around 40 times and fill the shelf. And then duplicate the shelf maybe 20 times, and fill the room. But when I do this my scene runs slower and slower until it crashes.

How would you do this the best way? It can not be the polycount that crashes the scene right? Its such so basic models. Should you copy or dupliacate?

Thank you!

use instances. these are memory-efficient copies that reference the original so any change to one affects them all. It's in the Edit/Duplicate Special menu. but I just write "instance" in the MEL command line since it's faster. If you've made the copies already and want to replace them with instances, I made a "Replace All With Last" script that is part of Facer that can replace your copies with instances:

But if you just want to speed up viewport display, try using bounding box display for objects you don't need to see in detail:

What I have noticed in the past is that a (really) high number of transforms slows Maya down.
If you can combine some objects as a single mesh (for example the shelf and the books) you will notice an increment in speed (and maybe less crashes).
