When you use Layer Previous, it undoes the most recent layer change or set
of changes made. Every change you make to layer settings is tracked and can
be undone with Layer Previous. You can use LAYERPMODE to suspend layer
property tracking when you don't need it, such as when you run large scripts.
There is a modest performance gain in turning off Layer Previous tracking.
Layer Previous does not undo the following changes:
■ Renamed layers. If you rename a layer and change its properties, Layer
Previous restores the original properties but not the original layer name.
■ Deleted layers. If you delete or purge a layer, using Layer Previous does
not restore it.
■ Added layers. If you add a new layer to a drawing, using Layer Previous
does not remove it.
Quick Reference
CHANGE
Changes the properties of existing objects.
CHPROP

LAYERP
Undoes the last change or set of changes made to layer settings.
LAYERPMODE
Turns on and off the tracking of changes made to layer settings.
PROPERTIES
Controls properties of existing objects.
PURGE
Removes unused items, such as block definitions and layers, from the drawing.
RENAME
