Tool shelf parameters

Hi

Well, in Blender 2.5, if you wanna add a new cylinder into the scene, you get in the tool shelf a new option called “Add cylinder” with all the necessary parameters like radius etc.
So much, when I start a new file, but when I’m trying to add a cylinder after I already began a new project, this menu doesn’t show up any more.

Am I doing something wrong or don’t I pay attention to something special or what is the clue behind it?

Greetings

N.B: I’m using build 2.54

You can bring up the tool shelf in Object Mode by pressing F6.

Wow, works great, thank you!! :smiley:
