Filtering a Feature Layer

Concept

Procedure

To filter a feature layer

1. If you are filtering by location, zoom the window to the extents of the selected feature class.
2. In Display Manager, select the feature layer and select the filter command.

   For example, in AutoCAD Map 3D, right-click the layer in the Display Manager and click Query To Filter Data.

3. Create an expression, using any of the following expression types:
   • Filtering by Location — Selects all features in a location you specify. Select one of the Locate On Map options and define a location in your drawing.

     For example, use a location expression to find all manholes in one section of town, or all parcels that touch a road, or all water pipes within 100 meters of a road.

   • Evaluating Properties— Selects all features that have the property value you specify. Insert a property, an operator, and a value.

     For example, to select all pipes with a diameter greater than 10, specify Diameter > 10.

     The Property list displays the properties available for this feature class. You can view and insert available values for a property from a list.

4. Optionally, add conditions to the expression.
5. Validate your expression.
6. Click OK to apply the filter.
