I'm trying to follow this guys tutorial. He's using Blender. I'm having a bit of trouble transfering the methods. How do you extrude vertecis the way her did. I got the sphere chopped, and pressed extrude and my geometry exploded, lol.

I was hoping it would let me haul them up like you can faces, but it did an automated thing..
