Filtering a Feature Layer (Concept)

Filtering a Feature Layer
Concept Procedure
 
 
 

Filter a feature source layer so that only some of the features appear in your map. Using a filter can help you improve performance when working with large sets of feature data.

To filter the layer, define a query condition or a set of conditions that specify which features you want. The procedure is similar to performing a search.

The result of a filter expression must be a Boolean value.

Tip In AutoCAD Map 3D, you can filter data after you bring it into your map, or you can use the Add To Map With Query option while bringing it in and then use Edit Query to apply a filter.
