To Filter Feature Layers

Filter one or more feature source layers so that only some of the features appear in your map.

To filter feature layers

1. In the Display Manager, select the layer, layers, or group to filter.

   Use Ctrl-click or Shift-click to select multiple layers.

2. Right-click any layer or group in the selection and click Query To Filter Data.
3. To add more feature layers to the data being searched by the expression, click Add Layer and select the layer to add. To delete a layer, select it in the list and click Delete.

   The list of layers at the top of the window shows any existing filters for the selected layers. If the layers use a common query (specifying a property that all the layers have in common), that query is listed separately.

4. If you are creating a location condition, click Zoom Extents to zoom the drawing window to the extents of the selected feature class.
5. Create a calculation for your search. You can create the following types of expressions:
   • Property Evaluation expressions compare the value of a property to a value you specify. For example, you can find parcels with an area greater than a value you specify, or streets with a particular number of lanes.
   • Location Conditions find data based on its location in the map. For example, you can draw a circle to find all parcels within that circle.
6. Validate your expression.
7. When the expression is complete and valid, click OK.

   When AutoCAD Map 3D has completed the search, it highlights both the selected rows in the Data Table and the associated features on your map.
