present in the saved drawing are considered reconciled (not new). Layers that
are added after a drawing is first saved are considered new unreconciled layers.
NOTE The layer baseline is created when the LAYEREVAL system variable is set to
1 or 2.
When a command that is set in the LAYERNOTIFY system variable is used,
the layer list is checked at that time and compared to the baseline. If there
are new layers, the Unreconciled Layers layer group is automatically created
and activated in the Layers palette.
Unreconciled layers become reconciled by using the Reconcile option of the
-LAYER command. Once a layer has become reconciled, it is removed from
the Unreconciled Layers layer group. After all new layers are reconciled, the
Unreconciled Layers layer group is removed.
NOTE You can reconcile multiple unreconciled layers at the same time.
Work with Layer States
You can save layer settings as named layer states. You can then restore, edit,
import them from other drawings and files, and export them for use in other
drawings.
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.
