HaloMods "Classic" Read-only Archive

I've exported the models of the AR and the pistol using Halo Map Tools. I've imported them into 3DS Max. I'm not very skilled with 3DS, so I need a little help. I try zooming in on the models, but they still seem tiny. If I zoom in too much they are not viewable.

How can a change the models so I can see them when I edit them?

Thanks.

Right click on the model and go to scale, and scale the model, dont zoom in on it.

Okay, so will that just be changing my view or the actual size? If its the size, I'll need to take it back down before exporting/ saving it right?
