||I did mean "shapefile" and not layer file. I regret I did not use the GIS lexicon proficiently enough in my origional post. Let me try again refering to the attached bitmap. The twelve polygons 10-1, 10-2 ... 12-1, refer to each of the 5,000,000 land parcels in my actual problem. The color coded areas refer to the mapbooks in my actual problem. There are about 3,000 of these in my actual problem. I want to create a new shape file which contains only areas represented by the grey, green and orange polygons. I have used a couple of different methods to accomplish this in the past. I have used the "intersect" tool. Which would be useful only if there were a smaller number of records and areas to geoprocess. I think the other better method I used was discribed in a online course example and it worked very well. The specific steps somehow involved using the color ramp symbology (grey, green, and orange in my example), then once the 5,000,000 records are symbolized into a color ramp, a new shape file with the 3,000 colored polygons can be saved which only have the polygons represented by the different ramped colors. I can't remember which version or extension allowed me to do this. Was it ArcView 3.x? or was it a separate ArcGIS Extension? Did this help clarify my origional question?
