[Gvsig_english] Problem with intersection

[virginia morales segura]

Hi Alexandra,

forgive my delay in replaying. I read your mail carefully for understand 
your trouble. You say that you have to split in three the country 
withouth cut any polygon, you can do it making a selection of a few 
polygons ( aproximately the third part) with the selection by polygon 
tool and intersect only those polygons. In the end you will have your 
info in separated shp that you can merge again in only one. In this way 
you can reduce the time of processing.

I hope it helps you, best regards.
