Reconcile New Layers
Unreconciled layers are new layers that have been added to the drawing and
have not yet been acknowledged by the user and manually marked as
reconciled.
Reconciling new layers is the process of manually reviewing new layers so that
you can avoid potential errors before plotting your drawing or when restoring
a layer state.
Unreconciled layers are new layers that have been added to the drawing or to
attached xrefs since the layer list was last evaluated. The layer list is checked
for new layers when a command, such as PLOT is used. In new drawings, the
layer baseline is created when the drawing is saved or plotted for the first time.
When a new drawing is first saved, the layer baseline is created, and all layers
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 Layer Settings dialog box or LAYEREVAL
system variable is used, the layer list is checked at that time and compared to
the baseline. If there are new layers, notification will display and the
