NO!!! I already know that, but apparently theres a way to better modify polygon primitives. Okay, let's say youre working on a nurb. You get the vertices up, then click hull to get the yellow dots. The yellow dots become a whole new area of manipulation to work with. Now, how do you get the "Hull" effect to show up on polygon primitives? I've seen it in a few videos, but they never fricken explain it.
