[3DSMax] Automatically mirror an object - how?

[Anonymous]

I wanted to start learning how to use 3DSMax by first making a sword model that could later be used for a game like Skyrim. But rather than making some simplistic, blocky sword, I wanted to jump to something more complicated to speed up the learning curve.

I was editing existing models in Blender before, so I already know more or less how to operate a program like this, and everything else can be covered with tutorials. But there's one thing I can't find a tutorial for...

Let me explain it on an example. I want to make a model of this sword:

The idea is that it's symmetrical and identical on both sides. I saw somewhere a video where a guy was somehow creating a model, and while he was working on one half, the other half was automatically updating and creating a perfectly symmetrical shape.

For this sword, I would be basically making only 1/4 of the sword, while the rest would be appropriately placed mirrors. I want this process of mirroring to happen automatically. How do I do that?
