How to slide geometry past an edge? I am trying to slide a bunch of selected edges past an edge, as is done at 19:27 of the blender guru tutorial on "how to make a beer".


AltRMB to select the edge loop
Press G twice
Move the mouse cursor up and down, while holding Alt


The edges only move down and also along the plane in which the circular loop resides (imagine for instance the top of the cylinder being the loop, and I'm trying to slide the edges to form a concavity in the cylinder)

I want the edges to move past the vertex loop.. Can someone help me?
With the vertices selected, press ShiftV to ensure that you are vertex sliding, not edge sliding. Pressing GG automatically picks between the two operators based on the selection, and you cannot edge slide geometry past adjacent edge loops (you can with vertex slide though). 

Once you are in the vertex slide operator, press C to disable clamp (or hold Alt). 



Note that disabling clamp locks the selected vertices to the edges which they are sliding on when you press C or Alt.



However in this particular situation I think GZ is a faster method, as mentioned by G.Rassovsky.
