Delete Deletes the selected layer filter. You cannot delete the All, All Used
Layers, or Xref filters. This option deletes the layer filter but not the layers in
the filter.
Properties Displays the
Layer Filter Properties dialog box, where you can
modify the definition of the selected layer property filter. This option is
available only when a layer property filter is selected.
Select Layers Temporarily closes the Layer Filter Properties dialog box so that
you can select objects in the drawing. This option is available only when a
layer group filter is selected.
■ Add: Adds the layers of the selected objects to the layer group filter that is
selected in the tree view.
■ Replace: Replaces the layers of the selected layer group filter with the layers
of the objects that are selected in the drawing.
List View
Displays layers and layer filters and their properties and descriptions.
If a layer filter is selected in the tree view, the list view 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 “Varies” is displayed for a layer filter, the
property is not the same for all layers in the filter.

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

if Plot is on.
Freeze Freezes the selected layers in all viewports, including the Model tab.
You can freeze layers to speed up ZOOM, PAN, and many other operations;
improve object selection performance; and reduce regeneration time for
complex drawings.
Objects on frozen layers are not displayed, plotted, hidden, rendered, or
regenerated.
Freeze the layers you want to be invisible for long periods. If you plan to switch
visibility settings frequently, use the On/Off setting to avoid regenerating the
