Ok this is my first map and i've gotten the hang of hammer pretty fast and its easy so far(for the most part). I am trying to touch up a few of my rooms and make them more detailed. As in many css maps there r vending machines, couches, chairs, ect. that u can use to black door ways and stuff. I can;t figure out the class/function name for that. I put my couch in and it either pushes me off the couch or i just walk right through it. Please Help. I can only move it by running into it..id like to move it by shooting it w/o breaking it...any tips would be appriciated.

Thank You in Advance!!
