<pre wrap="">Estamos a discutir este assunto neste momento no canal irc #qgis.
A resposta parece estar na pagina do formato dgn no site da biblioteca
OGR

"Creation Issues
2D DGN files may be written with OGR with significant limitations:
* Output features have the usual fixed DGN attributes. Attempts to
create any other fields will fail.
* ...
* ...
* ..."
me parece que não se possam arbitrariamente apagar todas as colunas de
um vector (shape, postgis, etc.) imagino que seja obrigatório que as
colunas se chamem de uma forma especifica, nomes provavelmente definidos
nas especificações do formato dgn, imagino eu.
De qualquer forma parece-me tb que possa haver problemas na biblioteca
ogr: abri um dgn em QGIS, que guardei como shapefile e tentei de guardar
outra vez como dgn... e deu o mesmo erro. A mesma coisa acontece ao
correr o programa ogr2ogr manualmente...
Será melhor perguntar na mailing list gdal/ogr.
Entretanto directamente do qgis hackfest
<a class="moz-txt-link-freetext" href="https://trac.osgeo.org/qgis/changeset/14562/">https://trac.osgeo.org/qgis/changeset/14562/</a>
[FEATURE] allow OGR save as without attributes (for eg. DGN/DXF)

<pre wrap="">Olá boa tarde,
Sou um utilizador recente de QGIS (v1.5, r13923M) e tenho tentado
exportar shapefile para dgn sem sucesso, obtendo o seguinte erro:
Export to vector file failed.
Error: creation of field Level failed (OGR error: CreateField() not
supported by this layer.)
Já alguém conseguiu realizar esta operação em ambiente QGIS?
obrigado
