To work with Guides in View menu
You can hide your guides when not using them and then display them only when they are needed.
To alternate between hidings and displaying the guides, choose the View tab from the Menu Bar and select Guides. The guides are visible when the icon appears pressed in.
Guides extend beyond the edges of image canvas so that you can align objects before placing them in the image. As you enlarge the image window, the guides extend from one edge to the other.
