How to use a component to remove material in Creo Parametric 2

I have been able to create a component in ProDesktop 8 and use it to remove material from an extruded block in order to make a two-part mould for casting. This video explains how to do it in ProDesktop but I want to do the same in Creo 2 but am a newbie and can't fint a Use Component option or Remove Material box. Any ideas Creo experts?
