Hi all,

I have some Microstation DGN file that are comprised of several layers =
of data.

How would I view only one layer at a time using a layer file?

Here is what I have to view the entire DGN file:

LAYER
   NAME "FDP_2001_dgn"
   TYPE LINE
   STATUS ON
   CONNECTIONTYPE OGR
   CONNECTION =
"d:/sclark1/server_data_copy/datasets/forest-data/TPL/fdp-dgn-utm/fdp_200=
1_utm.dgn"
  CLASS
 COLOR 0 255 0
  END
  PROJECTION
     "AUTO"
  END
  METADATA
    WMS_TITLE "FDP 2001"
    WMS_ABSTRACT "N/A"
    WMS_SRS "EPSG:26910"
  END
END

There are approximately 24 layers in the file.

Thanks,
Stephen
