Hey guys and gals, looking for some advice. I want to build a stadium type deal. Pretty big, maybe like nascar size?

Anyhow, obviously I only need to model one seat for the stadium, and I can duplicate that and what not. What I was really wondering, is if there is a way I can duplicate it, as a proxy or an instance or something like that? In otherwords in a way that it wont slow down my system to a crawl. I think with particles, you can make one model and then you do an instance and it wont kill your system.

What's the best way to go about this? I hope I made sense, thank you!!
