Is there is a way to create a ArcGIS 10 MODEL to: 1. batch select polygons from the same layer by attribute 2. merge these polygons into one 3. repeat this for all polygons shearing the same attributes

example: To create a geological map with all mapping polygons merged into one big polygon of the same lithology.

Cheers! M
