Import and Export Layer States
You can import layer settings from other drawings (DWG and DWT) and
export layer states (LAS).
If the layer state is imported from a drawing and it contains a layer property,
such as a linetype or plot style that is not loaded or available in the current
drawing, that property is automatically imported from the source drawing.
If the layer state is imported from an LAS file, and it contains linetype or plot
style properties that do not exist in the drawing, a message is displayed
notifying that the property could not be restored.
NOTE When a layer state contains more than one property that cannot be restored
from an LAS file, the message that displays only indicates the first property it
encountered that cannot be restored.
When importing a layer state from an LAS file or from another drawing that
are duplicates of layer states in the current drawing, you can choose to
overwrite the existing layer state or not import it.
Layer states can be imported into a previous release of the program.
Work with Colors
Color helps to group objects visually. You can assign colors to objects by layer
or individually.
Set the Current Color
You can use color to help you identify objects visually. You can assign the
color of an object either by layer or by specifying its color explicitly,
independent of layer.
Assigning colors by layer makes it easy to identify each layer within your
drawing. Assigning colors explicitly provides additional distinctions between
objects on the same layer. Color is also used as a way to indicate lineweight
for color-dependent plotting.
You can use a variety of color palettes when assigning color to objects,
