[Gvsig_english] Geoprocessing tools::strange error appears when trying to clip, intersect, ...

[Alvaro Zabala]

Hi Wolfgang!

The problem could be in the input layers.

What is the format of these layers? ¿SHP, DXF, GML or Postgis?

Sometimes, we see a DXF entity as a polygon, but internally it is a closed
polyline (and overlay geoprocessses like intersection, union, and so dont
work with polylines).

Another cause of error could be wrong geometries....etc

Could you send me to my private mail the files youre working with to make a
test?

Best regards.

Alvaro.
