How do I changing a structure shape in the model space?

I was trying to modify a building shape but the Help examples did not look like what I an seeing on my screen. I don't see the "handles" to modify a building shape like shown in Tutorial 14A.

The handles will not appear unless you have on of these two buttons active (the drawing tools).

I got that, but the actions from the tools don't seem to line up with the Help.  One example of the tool that I have no Idea what it's doing.  

I took a brand new building and I got the handles like the Help showed, so I'll work my way through a process.  I guess I have trail and error my way through to get the nuances of the tools  Thanks Chris, sometimes I need to talk out a problem.
