Hello, I am new to maya 2008 and I have purchased Learning Autodesk Maya 2008: The Modeling & Animation Handbook.

My problem is that I am in project 01 pg. 37, and I am trying to use the Edit>Duplicate Special to mirror my faces of Leon's Torso. I am wondering after that it says to set Geometry Type to Instace, but I am new to maya and I don't know where to find the Geometry Type.

Can anyone help me with my problem, and is there an better way to mirror faces?

Thanks in advance
