Dear listers
 
Apologies if I am re-treading old ground....
 
I have a table of c. 25 000 objects imported from another application. Some of these objects were originally drawn as "donut" polygons (for example archaeological monuments like ring ditches with an inner and outer line to show the width of the ditch). I would like to combine these occurances into one polygon but need to find them first. Is there is simple way to find one object that lies entirely within another object in the same table, I don't understand the error messages I am getting when I attempt this. Thanks
