How do I adjust things in 3d in after effects I have multiple layers I now wish edit them in 3 dimensions. So I check the 3d layer attribute, but I still cant move the elements in that layer. In a youtube video (7:45) i have been following, when the user clicks on the 3d layer option, an axis appears on the the element, and it can be enlarged and moved. 

See picture: 



However no such axis appears when I check the 3d layer option. Do I need to enable it somewhere in the options?
I pressed CTRL + SHIFT + H and my controls were back
