Prevent Objects from Being Selected
You can prevent objects on specified layers from being selected and modified
by locking those layers.
Typically, you lock layers to prevent accidental editing of particular objects.
Other operations are still possible when a layer is locked. For example, you
can make a locked layer current, and you can add objects to it. You can also
use inquiry commands (such as LIST), use object snaps to specify points on
objects on locked layers, and change the draw order of objects on locked layers.
