Change Layer Settings and Layer Properties
You can change the name of a layer and any of its properties, including color
and linetype, and you can reassign objects from one layer to another.
Because everything in your drawing is associated with a layer, it's likely that
in the course of planning and creating a drawing, you'll need to change what
you place on a layer or how you view the layers in combination. You can
■ Reassign objects from one layer to another.
■ Change the name of a layer.
■ Change the default color, linetype, or other properties of the layer.
Reassigning an object to a different layer is useful if you create an object on
the wrong layer or decide to change your layer organization. Unless the color,
linetype, or other properties of the object have been set explicitly, an object
that you reassign to a different layer will acquire the properties of that layer.
You can change layer properties in the Layer Properties Manager and in the
Layer control on the Layers toolbar. Click the icons to change settings. Layer
names and colors can be changed only in the Layer Properties Manager, not
the Layer control.
Changes in the Layer Properties Manager can be grouped by enabling Combine
Layer Property Change option in User Preferences tab in the Options dialog
box. Layer creation and deletion will be tracked in the Undo list as unique
items.
To change the layer of one or more objects
1 Select the objects whose layer you want to change.
