Save, Restore, and Edit Layer States
You can save the current layer settings in a drawing as a named layer state and
restore them later.
Saving layer settings is convenient if you need to return to particular settings
for all layers during different stages in completing a drawing or for plotting.
Save Layer Settings
Layer settings include layer states, such as on or locked, and layer properties,
such as color or linetype. In a named layer state, you can choose which layer
states and layer properties you want to restore later. For example, you can
choose to restore only the Frozen/Thawed setting of the layers in a drawing,
ignoring all other settings. When you restore that named layer state, all settings
remain as they are currently set except whether each layer is frozen or thawed.
Save Layer Property Override Settings
When layers contain viewport property overrides, those settings are saved to
a layer state when the viewport that contains overrides is active.
If the layer state is saved from model space, any layer property override settings
are not included. This is because only one value can be saved for each layer
property in a layer state. If layer property overrides need to be saved in the
layer state, make the viewport active on the layout tab and then save the layer
state.
Restore Layer Settings
When you restore a layer state, the layer settings (layer states and layer
properties) that were specified when the layer state was saved are restored.
You can specify specific settings to restore with the Restore and Edit options
of the -LAYER command. The layer property settings that are not selected
remain unchanged in the drawing.
NOTE To be notified when new layers are added to the drawing, use the LAYEREVAL
and LAYERNOTIFY system variables.
When restoring layer states, the following additional behaviors can occur
■ When restoring a layer state, the layer that was current when the layer
state was saved is made current. If that layer no longer exists, the current
layer does not change.
