The "ERROR 6" indicates that it is a GDAL/OGR error, not a GRASS GIS error (for the export we make use of GDAL, hence "outsource" the creation of the desired format). I found this in the internet: https://lists.osgeo.org/pipermail/gdal-dev/2006-February/008089.html which is exactly the same error message: Frank Warmerdam, Feb 28 15:12:15 EST 2006: > The CreateField() messages are expected with DGN output.

Note that, to prevent GRASS from creating the CAT column -c should be -s: https://grass.osgeo.org/grass78/manuals/v.out.ogr.html -s Skip export of GRASS category ID ('cat') attribute HTH, Markus _______________________________________________ grass-user mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/grass-user
