I'm working through Dariush Derakhshani's "Introducing Autodesk Maya 2013," but I'm stuck on a portion where he asks you to move an edge within a model. When I select the edge and try to move it, the entire model moves with it instead. The tutorial looks like the edge should 'slide about' within the model vs. moving the entire model... specifically this is the 'hand' tutorial. Any help would be greatly appreciated.
