Hello everyone

I began learning Revit MEP a set of tutorial video. I got stuck at the part where I shall add the plenum level. In the video it tell me to click --- architect tap ---> level ----> Change element type. In my Ribbon it does not give me an option for Change element type. I am using Revit MEP 2011 and the tutorial was for MEP 2010.

Please help me to get thru this lesson.
