Preferences question

I have noticed in many tutorials for Maya that when creating a NURBS or a polygon such as a circle or square the shape appears as a full object. I am running Maya 2010 and when I select an object the program asks me to click on the grid and drag to the size I what. i am pretty sure that this is some sort of preference setting but I cannot find it. Thanks for any help in advance.
