Define a Layer Property Filter
A layer property filter is defined in the Layer Filter Properties dialog box, where
you select any of the following properties you want to include in the filter
definition:
■ Layer names, colors, linetypes, lineweights, and plot styles
■ Whether layers are in use
■ Whether layers are turned on or off
■ Whether layers are frozen or thawed in the active viewport or all viewports
■ Whether layers are locked or unlocked
■ Whether layers are set to be plotted
You use wild-card characters to filter layers by name. For example, if you want
to display only layers that start with the letters mech, you can enter mech*.
See “Wild-Card Characters” for a complete list.
The layers in a layer property filter may change as the properties of the layers
change. For example, if you define a layer property filter named Site that
includes all layers with the letters site in the name and a CONTINUOUS
linetype, and then you change the linetype of some of those layers, the layers
with the new linetype are no longer part of the Site filter and are not displayed
when you apply that filter.
Layer property filters can be nested under other properties filters or under
group filters.
Define a Layer Group Filter
A layer group filter includes only those layers that you explicitly assign to it.
If the properties of the layers assigned to the filter change, the layers are still
part of the filter. Layer group filters can be nested only under other layer group
filters.
TIP Layers from the layer list can be included in a filter by clicking and dragging
the selected layers to the filter.
Invert a Layer Filter
You can also invert a layer filter. For example, if all the site plan information
in a drawing is contained in multiple layers that include the word site as part
of the layer name, you can display all information except site plan information
