Could somebody advise, how I can combine (merge) different objects of a shp theme with equal meaning of one attribute of a field (in ArcMap)? I have shp theme with many objects, in the field "A" some of them have value “1”, some others “2”, others – “3”, etc I need to combine all object with A=1 in a single object, all objects with A=2 – in a single as well, etc for all objects of the shp theme.

It seems very simple operation, but I can’t find this possibility in ArcMap. ((

It sounds like what you want is "dissolve":

Dissolve (Data Management)


Aggregates features based on specified attributes. http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//00170000005n000000
