Filters the list of layers based on the criteria that you specify.
When a layer filter is selected in the Filters panel of the Layer Properties Manager, only the layers that match the properties specified in the filter are displayed in the layer list. Filtering layers reduces a long list of layers to only those that are currently relevant.
List of Options
The following options are displayed.
Filter Name
Displays the name of the layer properties filter.
Filter Definition
Displays the properties of layers that determine which layers are listed. You can click to specify one or more properties to define the filter. All the properties specified on a single line in the filter definition must be true to display a layer name (a logical AND). Subsequent lines in the filter definition each specify alternative criteria (a logical OR).
Here is an example:
This filter has been named Mechanical, and the filter definition includes the following criteria:
- The layer name must contain the letters "mech", and be turned on, and be thawed, or . . .
- The layer must be locked and its color must be red.
