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.
To help you differentiate
between locked and unlocked layers, you can do the following:
- Hover over an object to see whether a
lock icon is displayed
- Dim the objects on locked layers
NoteGrips are not displayed
on objects that are on locked layers.
