-Layer

? to list

Lists the names of layers in the current drawing. Press F2 to flip to the Prompt window to see the list. Use wildcards, such as ? and *, to narrow down the list of names.

New layer

Creates new layers; prompts you:

Names for new layers - (enter one or more layer names. To create several new layers at the same time, separate each name with a comma, such as doors,windows,walls.)

Make new current layer

Creates a new layer, and then makes it current. This option combines the New and Set options; prompts you:

New layer to make current - (enter a layer name; only one layer may be current.)

Set layer as current

Sets a layer as the current one; prompts you:

New layer to make current - (enter a layer name; only one layer may be current.)

Color

Changes the color of layers; prompts you:

1. Color - (specify the color by number or name; see the Color command.)

2. Layer(s) to be color <layername> - (specify the layer names or press Enter to change the color of the most-recently used layer; separate more than one layer name with commas.)

Linetype

Changes the linetype of layers; prompts you:

1. Linetype: ? to list <Continuous> - (enter an linetype name or an option);  see the Linetype and -Linetype commands
   
   ? to list - Lists the names of linetypes defined in the current drawing

2. Layer(s) for linetype CONTINUOUS <CurrentLayer> - (enter the name(s) of layers, separating names with a comma, or else press Enter to apply the linetype to the default layer.)

LineWeight

Changes the lineweight of layers; prompts you:

1. Enter lineweight (0.00 - 2.11mm) - (enter a number between 0.00 and 2.11.)

2. Enter name list of layers(s) for lineweight 0.00 mm <CurrentLayer> - (enter the name(s) of layers, separating names with a comma, or else press Enter to apply the line weight to the default layer.)

TRansparency

Sets the entity transparency factor between 0 (fully opaque) and 90 (fully transparent); prompts you:

• Enter transparency (0 - 90) - (enter a number between 0 and 90; default is 0.)
• Layer(s) for transparency 0 <CurrentLayer> - (enter the name(s) of layers, separating names with a comma, or else press Enter to apply the transparency level to the default layer.)           

The 2DWireframe visual style ignores this setting; for it, use the TRANSPARENCYDISPLAY variable to control the level of transparency.

MATerial

Sets the material property for all entities on the layer; prompts you:

1. Material: ? to list/<Global> - (enter an option):
   
   ? to list - Displays a list of the materials and their description in the Prompt History window

2. Layer(s) for material GLOBAL <CurrentLayer> - (enter the name(s) of layers, separating names with a comma, or else press Enter to apply the material to the default layer.)

The default material is Global, which cannot be deleted or renamed. When you need to add more materials to the drawing, see the Materials command.

Plot

Changes the plot status of layers (plot or no plot); prompts you:

1. Enter a plotting preference [Plot/No] <Plot> - (enter an option.)

2. Enter layer name(s) for this plot preference <CurrentLayer> - (enter the name(s) of layers, separating names with a comma, or else press Enter to apply the plot status to the default layer.)

stAte

Creates, edits, renames, restores, deletes, imports, and exports layer states. See the LayerState command. Prompts you:

Enter an option [? to list layer states/ Save/ Restore/ Edit/ reName/ Delete/ Import/ eXport] - (enter an option):

• ? to list layer states - lists the names of saved layer states and their description in the Prompt History window
• Save - saves the current layer state; prompts you:

1. Enter a name for the new Layer State - (type a name.)

2. Enter state to change [On/ Frozen/ Lock/ Color/ lineType/ lineWeight/plot Style/ Plot/New vp frozen] - all states are on by default; (enter a state name to toggle its setting.)

• Restore - Restores a saved layer state; prompts you:

1. Enter name of Layer State to restore or [?] - (type the name of saved layer state or type ? to list the saved layer states.)

• Edit - Edits a saved layer state. prompts you:

1. Enter the name of the Layer State to edit or [?] - (type the name of saved layer state or type ? to list the saved layer states.)

• Rename - Renames a saved layer state; pPrompts you:
• Type the name of saved layer state or type ? to list the saved layer states - (type the name of saved layer state or type ? to list the saved layer states.)
• Enter the new name - (type the new name for the selected layer state.)
• Delete - deletes a saved layer state; prompts you:
• Enter the name of the Layer State to delete or [?] - (type the name of saved layer state or type ? to list the saved layer states.)
• Import - imports a layer state from a file into the current drawing:

1. Displays a File dialog. Select a layer state file (*.las).

2. Click the Open button

• Export - exports a saved layer state in the current drawing to a layer state file (*.las). Prompts you:

1. Enter the name of the Layer State to export or [?] - (type the name of saved layer state or type ? to list the saved layer states.)

2. Displays a File dialog. Type a name for the layer state file, then press the Save button.

turn layer ON

Turns layers on that had been turned off with the OFf option; prompts you:

Layer(s) to turn ON - (specify the names of layer name(s) to turn on; separating multiple layer names with commas.)

turn layer OFf

Turns layers off to hide their entities from view; prompts you:

Layer(s) to turn OFF - (specify the names of layer name(s) to turn off; separating multiple layer names with commas.)

The current layer cannot be turned off.

When layers are off, they are hidden from view. In most cases, you should probably use the Freeze option, as it offers more features.

Freeze

Freezes layers so that they are hidden from view; prompts you:

Layer(s) to Freeze - (specify the names of layer name(s) to freeze; separating multiple layer names with commas.)

The current layer cannot be frozen.

When layers are frozen...

• Entities are hidden from view
• Entities cannot be edited
• The extents of entities are ignored when the program calculates the drawing extents
• Entities are not included in operations, such as ViewBase, Print, Export, and PDFout.

Thaw

Thaws layers that were previously hidden with the Freeze option; prompts you:

Layer(s) to Thaw - (specify the names of layer name(s) to thaw; separating multiple layer names with commas.)

LOck

Locks layers so that their entities remain visible but cannot be edited; prompts you:

Layer(s) to Lock - (specify the names of layer name(s) to lock; separating multiple layer names with commas.)

The current layer can be locked.

Unlock

Unlocks layers that were locked form editing with the LOck option; prompts you:

Layer(s) to Unlock - (specify the names of layer name(s) to unlock; separating multiple layer names with commas.)
