This process adds a blank layer to the active PDF. This layer will be completely empty.

1. Go to View > Tabs > Layers or press ALT+Y to show the Layers tab.
2. If there are no layers in the PDF currently, click Add New Layer on the Layers tab toolbar. Otherwise, determine where in the layers list you would like the new layer to be placed:
   • Before an existing layer: Select the desired layer and go to Add New Layer > Add Before.
   • After an existing layer: Select the desired layer and go to Add New Layer > Add After.
   • As the child of an existing layer: select the desired layer and go to Add New Layer > Add Child.
   • At the end of the Layers list: ensure that no Layer is selected and click Add New Layer.
3. Enter a name for the layer and click OK.

To assign markups to an existing layer, simply CTRL-click the desired markup or, in the case of multiple markups, multi-select them and CTRL-click one of them, then go to Layer and select the desired Layer.

Note: If you flatten a markup that is associated with a layer, it will flatten to that layer.
