How to create collision for created weapon?

[GokuCZ]

Hello. I have a little problem.

 

How do I create collision for my created sword?

 

I looked up tutorials online, they are out of date or they skip crucial parts in process.

 

I am using 3ds max 2010.

 

I tried to use blender because of some tutorials, however when i want to import NIF file into blender, i go to file>import>choose my file with right click>Import NIF

and instead of opening the file this happens http://i.imgur.com/ygorg.jpg and the actual model is nowhere to be found.

 

So first of all, how do I create collision for weapons using 3DS max?

What am I doing wrong when importing NIF into blender?

 

Thank you
