Layers provide the capability to incorporate more than one level of objects into a drawing. Each added layer builds on top of the previous created layer to create a multidimensional drawing. They are managed and controlled through the Layers Panel, which appears as shown below when the Layers option is selected in the Info Menu.
Click or Tap on the corresponding Layers Panel item name to learn more about what the option does.
The Add Button adds a layer to the bottom of the layer list.
The Delete Button removes the top layer from the layer list.
The Move Up Button moves a selected layer up one level in the layer list.
The Move Down Button moves a selected layer down one level in the layer list.
The Layers Settings Menu contains options for adding, deleting, re-ordering, and merging layers.
The Visibility option is an "On/Off" toggle button for setting the visibility of each created layer. It appears to the right of each layer name in the list as an "eye" icon and indicates the visibility of the layer. To hide (or show) a layer, simply Tap on the eye icon of the layer to be toggled. An eye icon with a line through it indicates that a particular layer is not visible, whereas an eye with no line indicates a layer is visible.
The Lock option is an "On/Off" toggle button for locking or unlocking a layer. It is located to the right of the visibility icon and indicates whether or not a layer is locked. To lock (or unlock) a layer, simply Tap on the lock icon of the layer to be toggled. A closed lock icon indicates that a layer is locked and an open lock icon indicates a layer is unlocked.
Note: Layers located at the top of the Layers List are drawn above the layers below it.
