ADOBE ACROBAT 3D VERSION 8 365 User Guide Note: A Lock icon in the Layers panel indicates that a layer is for information only. Locked layers can be created from AutoCAD and Visio files. Use the Layer Properties dialog box to change the visibility of a locked layer. A B C Layers panel A. Eye icon indicates a displayed layer B. Locked layer C. Hidden layer 1 Choose View > Navigation Panels > Layers, and then do one of the following: • To hide a layer, click the eye icon. To show a hidden layer, click the empty box. (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.) • To show or hide multiple layers, choose an option from the Options menu in the Layers panel. 2 From the Options menu in the Layers panel, choose one of the following: List Layers For All Pages Shows every layer across every page of the document. List Layers For Visible Pages Shows layers only on the currently visible pages. Reset To Initial Visibility Resets layers to their default state. Apply Layer Overrides Displays all layers. This option affects all optional content in the PDF, even layers that are not listed in the Layers panel. All layers are visible, regardless of the settings in the Layer Properties dialog box. You cannot change layer visibility using the eye icon until you deselect this command. You can edit layer properties in the Layer Properties dialog box, but changes (except changes to the layer name) are not effective until you choose Reset To Initial Visibility in the Options menu. Note: You cannot save the view of a layered PDF by using the eye icon in the Layers panel to show and hide layers. When you save the file, the visibility of the layers automatically reverts to the initial visibility state. If you want to save a different view of a layered PDF, you must change the default state of the layers in the Layer Properties dialog box. Edit layer properties You can combine the default state setting, the visibility setting, and the print setting to control when a layer is visible and when it prints. If a layer contains a watermark, for example, you may want the layer to not show on-screen but always to print and always to export to other applications. In this case you can set the default state to on, the initial visibility to never visible (the image doesn't show on-screen), and the initial print and initial export states to always print and always export. The layer need not be listed in the Layers panel, since all the state changes are handled automatically.
