I apologise in advance if it's been answered before. I'm relatively new to blender and have been following this timelapse video (https://www.youtube.com/watch?v=wRzYBsTvnXY). At around 7:37, it seems the creator can extrude the vertices along the x-axis (or in any axes).
From what I'm seeing is, he first selected (Ctrl) two vertices then extruded (E) using the mouse. Am I missing something? Or do I have to do some custom settings? I'm aware that there're some major updates from 2.79b to 2.8 but this is not changed, right?
