I'm importing these impossibly large models of cityscapes that my coworkers have created, keep a few elements of them, and delete the rest. I've gotten that far successfully, however once I do that I've noticed that as I try to pan around my workspace the center of my little "universe" is no longer at the center of that tiny grid. It's at some unmarked location off the grid.

Does anyone know how to reset this point back to the center of my grid?

Please forgive me if I don't know the correct terminology. I've just had this software dropped in my lap and I'm trying to start somewhere.

Thanks.
