Hello there,

I'm new to ArcGIS and absolutely not sure wether I ask my question in the right place (probably not).

I am working with ArcGIS 10 and I have a series of shapes that represent lots of polygons. Each polygon is caracterized by a field that defines its name. Those names are quite often really long and complex, so I wanted to add a field to each of these (about 200) shapes and give a code according to each name of the polygon. Is there any possibility of doing that automatically? Thank you for your answers and sorry for posting this question in the wrong thread.

You can add a field and then use the Field Calculator to populate the new field's values according to other values within the table. The following Help documents should help you create the field and then get to the field calculator. You can also script in incremental values if desired. If you need help developing an expression based off other fields in the table, let us know.
