You can add, delete, and rename layers, change their properties, set property overrides
in layout viewports, and add layer descriptions. The Layer Property Manager includes
a Filters panel and a layer list panel. Layer filters control which layers are displayed
in the layer list, and can also be used to make changes to several layers at a time.

The Layer Properties Manager is alway updated and displays the current state of the
layer properties and filter selection in the current space: model space, a paper space
layout, or in model space in a layout viewport.

List of Options

The following options are displayed.

Current Layer

Displays the name of the current layer.

The current layer is displayed in the top-left corner of the Layer Properties Manager.
The current layer is also indicated by a green check mark in the layer list.

Search for Layer

Filters the layer list by name as you enter characters in the box.

Search for Layer is located in the top-right corner of the Layer Properties Manager.

New Property Filter

Displays the Layer Filter Properties dialog box, where you can create a layer filter
based on layer settings and properties.

New Group Filter

Creates a layer filter that contains layers that you select and drag to the filter.

Layer States Manager

Displays the Layer States Manager, where you can save the current property settings
for layers in a layer state and then restore those settings later.

New Layer

Creates a new layer with a default name that you can immediately change. The new layer
inherits the properties of the currently selected layer in the layer list.

The new layer is created below the last currently selected layer.

New Layer Frozen VP In All Viewports

Creates a new layer and freezes it in all existing layout viewports. This button is
accessible from the Model tab or layout tabs.

Delete Layer

Deletes selected layers. You can delete only unreferenced layers. Referenced layers
include layers 0 and DEFPOINTS, layers containing objects (including objects in block
definitions), the current layer, and xref-dependent layers.

Layers in a partially opened drawing are also considered referenced and cannot be
deleted. (Not applicable to AutoCAD LT.)

NOTE: Be careful about deleting layers if you are working on a drawing in a shared project
or one based on a set of layering standards.

Set Current

Sets the selected layer as the current layer. New objects are automatically created
on the current layer. (CLAYER system variable)

Status Line – Located at the bottom of the Layer Properties Manager

Shows the name of the current filter, the number of layers displayed in the list view,
and the number of layers in the drawing.

Invert Filter

Displays all layers that do not meet the criteria in the selected layer filter.

Indicate Layers in Use

Displays icons in the list view to indicate whether layers are in use. (SHOWLAYERUSAGE
system variable)

In a drawing with many layers, clear this option to improve performance.

Refresh

Refreshes the order of the layer list and the layer status information.

Settings

Displays the Layer Settings dialog box, where you can set various display options.

Filters Pane

Displays a hierarchical list of layer filters in the drawing, which control the layers
listed in the Layer Properties Manager. The top node, All, lists all the layers in
the drawing.

In the Filters pane, you can do the following operations:

• Expand a node to see nested filters. Right-click a property filter New Properties Filter to open the Layer Filter Properties dialog box and view the
  definition of the filter.
• Click the buttons control the display of the Filters pane.
• When the Filters pane is collapsed, use the Layer Filter button () at the bottom-left corner of the Layer Properties Manager to display a list of filters.

Additional layer filters are displayed under the following circumstances:

• If there are xrefs attached to the drawing, an Xref node displays the names of all
  the xrefs in the drawing and their layers. Layer filters defined in xref files are
  not displayed. Additionally, an All non-Xref Layers node displays the names of all
  layers that are not referenced from other drawings.
• If there are layers that contain property overrides, a Viewport Overrides node displays
  those layers and the properties that contain overrides. The Viewport Overrides filter
  is displayed only when the Layer Properties Manager is accessed from a layout tab.

• If there are new layers that have been added to the drawing since the layer list was
  last evaluated (depending on the LAYERNOTIFY system variable), an Unreconciled New
  Layers filter displays new layers that need to be reconciled.

Filters Shortcut Menu

Provides commands to be applied to the layers included in the filters you select in
the Filters pane, including the All and All Used Layers filters.

Visibility

Changes the visibility state of the layers in the selected filters.

Lock

Controls lock state of the layers in the selected filters.

Viewport

In the current layout viewport, controls the VP Freeze setting of the layers in the selected filters.

Isolate Group

Freezes all layers that are not included in the selected filters.

• All Viewports. In all layout viewports, sets VP Freeze for all layers that are not included in the
  selected filters. In model space, freezes all layers that are not in the selected
  filter, with the exception of the current layer.
• Current Viewport Only. In the current layout viewport, sets VP Freeze for all layers that are not included
  in the selected filters. In model space, turns off all layers that are not included
  the selected filters, with the exception of the current layer.

New Properties Filter

Displays the Layer Filter Properties dialog box, where you can create a new layer
property filter based on layer names and layer property settings such as color and
plot style.

New Group Filter

Creates a new layer group filter. Enter a new name. Select the All filter or any other
layer filter in the tree view to display layers in the list view, and then drag layers
from the list view into the new layer group filter in the tree view.

Convert to Group Filter

Converts the selected layer property filter to a layer group filter.

Rename

Renames the selected layer filter.

Delete

Removes the selected layer filter. You cannot delete the All, All Used Layers, or
Xref layer filters.

Properties

Displays the Layer Filter Properties dialog box, where you can modify the definitions
of selected layer property filters. This option is available only when a layer property
filter is selected.

Select Layers

Adds or replaces layers in the selected layer group filter. This option is available
only when a layer group filter is selected.

• Add. Adds layers to the selected layer group filter from the objects selected in the drawing.
• Replace. Replaces the layers of the selected layer group filter with the layers of the objects
  that are selected in the drawing.

Layer List Pane

Displays layers and layer filters and their properties and descriptions.

If a layer filter is selected in the Filters pane, the layer list pane displays only
the layers in that layer filter. The All filter in the tree view displays all layers
and layer filters in the drawing. When a layer property filter is selected and there
are no layers that fit its definition, the list view is empty. To modify a property
of a selected layer or of all layers in a selected filter, click the icon for that
property. When a mixed icon or “Variesâ€‌ is displayed for a layer filter, the property
is not the same for all layers in the filter.

Status

Indicates the type of item: layer filter, layer in use, empty layer, or current layer.

— Layer is the current one

— Layer is in use

— Layer is not in use

— Layer is in use, and a property override is turned on in a layout viewport

— Layer is not in use, and a property override is turned on in a layout viewport

NOTE:To improve performance, this column is turned off by default, displaying the icon instead.

Name

Displays the name of the layer or filter. Press F2 to enter a new name.

On

Turns the selected layers on and off. When a layer is on, it is visible and available
for plotting. When a layer is off, it is invisible and not plotted, even if Plot is
on.

Freeze

Freezes the selected layers in all viewports, including the Model tab. You can freeze
layers to improve performance and reduce regeneration time in complex drawings.

Objects on frozen layers are not displayed, plotted, hidden, or regenerated.

In drawings that support 3D modeling, they are not rendered. (Not applicable to AutoCAD
LT.)

TIP:Freeze the layers that you want to remain invisible for long periods. If you plan
to switch visibility settings frequently, use the On/Off setting to avoid regenerating
the drawing. You can freeze a layer in all viewports, in the current layout viewport,
or in new layout viewports as they are created.

Lock

Locks and unlocks the selected layers. Objects on a locked layer cannot be modified.

Color

Changes the color associated with the selected layers. Clicking the color name displays
the Select Color dialog box.

Linetype

Changes the linetype associated with the selected layers. Clicking the linetype name
displays the Select Linetype dialog box.

Lineweight

Changes the lineweight associated with the selected layers. Clicking the lineweight
name displays the Lineweight dialog box.

Transparency

Controls the visibility of all objects on the selected layer. When transparency is
applied to individual objects, the objects’ transparency property overrides the transparency
setting of the layer. Clicking the Trasparency value displays the Layer Transparency
dialog box.

Plot Style

Changes the plot style associated with the selected layers. If you are working with
color-dependent plot styles (the PSTYLEPOLICY system variable is set to 1), you cannot
change the plot style associated with a layer. Clicking the plot style displays the
Select Plot Style dialog box.

Plot

Controls whether the selected layers are plotted. If you turn off plotting for a layer,
the objects on that layer are still displayed. Layers that are off or frozen are not
plotted, regardless of the Plot setting.

New VP Freeze

Freezes selected layers in new layout viewports. For example, freezing the DIMENSIONS
layer in all new viewports restricts the display of dimensions on that layer in any
newly created layout viewports but does not affect the DIMENSIONS layer in existing
viewports. If you later create a viewport that requires dimensions, you can override
the default setting by changing the current viewport setting.

VP Freeze (available only from a layout tab)

Freezes selected layers in the current layout viewport. You can freeze or thaw layers
in the current viewport without affecting layer visibility in other viewports.

VP Freeze is an override to the Thaw setting in the drawing. That is, you can freeze
a layer in the current viewport if it’s thawed in the drawing, but you can’t thaw
a layer in the current viewport if it’s frozen or off in the drawing. A layer is not
visible when it is set to Off or Frozen in the drawing.

VP Color (available only from a layout tab)

Sets an override for the color associated with the selected layer for the active layout
viewport.

VP Linetype (available only from a layout tab)

Sets an override for the linetype associated with the selected layer for the active
layout viewport.

VP Lineweight (available only from a layout tab)

Sets an override for the lineweight associated with the selected layer for the active
layout viewport.

VP Transparency (available only from a layout tab)

Sets an override for transparency associated with the selected layer for the active
layout viewport.

VP Plot Style (available only from a layout tab)

Sets an override for the plot style associated with the selected layer for the active
layout viewport. Override settings are not visible in the viewport or plotted when
the visual style in the drawing is set to Conceptual or Realistic. If you are working
with color-dependent plot styles (the PSTYLEPOLICY system variable is set to 1), you
cannot set a plot style override.

Description

(Optional) Describes the layer or the layer filter.

List View Shortcut Menus

Provides options for modifying the list and modifying selected layers and layer filters.
