Summary
Undoes changes you have made to layer settings such as color or linetype. If settings are restored, a message is displayed: “Restored previous layer states.”
When you use Layer Previous, it undoes the most recent change using the Layers palette or -LAYER command. Every change you make to layer settings is tracked and can be undone by Layer Previous.
LAYERP (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 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.
