I have a really simple question I can't find the answer to. I'm looking to delete a range of values from an attribute table in ArcGIS 10. I'm looking for a quick way to delete about 3000 records. The idea is to have some blank records so when I do a dissolve in order to form polygons, the 3000 tiny polygons are no longer there and only larger polygons are dissolved to form bigger polygons on the basis of the same column contents.
So I basically have 2 questions:
How do I delete a range of 3000 records from the attribute table, by FID range or any other efficient method?
Will blank cell contents prevent records from being included in a dissolve?
(Or 3., is there any way of creating a conditional dissolve which avoids a range of records according to FID/other column value?)
