   • Select all or none of the features from a specific category by right clicking on it and then selecting All or None.

3. Select All to extract every feature identified in the Interoperability dialog box, View to extract only the actual view and Fence to extract features inside a fence.
4. Click on the Map to start the query process.
   Note: Only click once on the map. The extraction process will restart for each time a click was made on the map.
