Navigating the Project

...

At the top of the Contents pane, there is a series of seven buttons. By default, the leftmost button is selected, : List by Drawing Order.

When this button is selected, the order in which the layers are listed corresponds to the order in which the layers are visually stacked in the Map view. To test how the drawing order works, let's you will reorder the layers.

1. In the Contents pane, click and hold the Census_2010_By_SuperNeighborhood layer name and drag and drop it above the Major_Roads layer.

You will notice that, in the Map view, the Census_2010_By_SuperNeighborhood layer is now drawn in on top of the Major_Roads layer, meaning that freeways are only visible in areas not covered by a super neighborhood. It is possible to add transparency to the super neighborhood layer or to symbolize it with a bold outline and a hollow fill, but, in general, it is best to have polygon layers at the bottom, so we will return the layers to their previous order.
