Just a comment on that: In order to build the DWG driver, you or your company, need to be part of some kind of alliance to be able to download a full version of the Teigha SDK. AFAIK

I just want to add that Teigha, which can currently be used to open DWG in GDAL, does support DGN version 8. So, if someone wants to add that support, I'd suggest looking at the DWG driver. The DWG driver has: class OGRDWGServices : public ExSystemServices, public ExHostAppServices You'd need to have something like: class OGRDGNServices : public OdRxSystemServices, public OdDgHostAppServices I would not be surprised if considerable chunks of the DWG driver could be generalized to work for both DWG and DGN, André > Is it possibly to get the originator to > provide it in some other format (e.g. DXF, noting that will lose the > georeferencing)? > > Brad > _______________________________________________ > gdal-dev mailing list > gdal-dev@lists.osgeo.org > http://lists.osgeo.org/mailman/listinfo/gdal-dev _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
