Viewing layers
Some applications, such as Adobe InDesign, AutoCAD, and Visio, allow layers to be 
added to documents. When such documents are exported to Adobe PDF, these layers 
appear in the Layers tab. You cannot create layers in Adobe Reader. However, you can 
examine layers and show or hide the content associated with each layer by using the 
Layers tab in the navigation pane. 
Layers tab A. Eye icon indicates a displayed layer. B. Hidden layer
You can select or copy content in a layered Adobe PDF document using the Select tool or 
the Snapshot tool. 
A Lock icon in the Layers tab indicates that a layer is for information only. The layer's 
visibility cannot be changed.
To view layers:
1.  Click the Layers tab on the left side of the window, or choose View > Navigation Tabs > 
Layers.
2.  Click the eye icon 
 to hide a layer's content. Click the empty box to show a hidden 
layer's content. A layer is visible when the eye icon is present, and hidden when the eye 
icon is absent. This setting temporarily overrides the settings in the Layer Properties 
dialog box.
3.  From the Options menu in the Layers tab, do any of the following:
●     
Choose List Layers For All pages to show every layer across every page of the document.
●     
Choose List Layers For Current Page to show layers only on the currently visible page.
●     
Choose Reset To Initial Visibility to reset layers to their default state.
●     
Choose Apply Layer Overrides to display all layers. This option affects all optional 
content in the PDF document, even layers that are not listed in the layers tab. All layers 
are visible, regardless of the settings in the Layers Properties dialog box. You cannot 
change layer visibility using the eye icon until you toggle this command off.
