[Qgis-user] Fwd: Import _and_ process DXF?

[Andreas Neumann]

Hi,

While gdal 1.7 already creates dxf read/write support, it cannot yet be
reliably used with QGIS. QGIS would first have to be optimized to handle
the geometry that gdal sends and to interpret OGR feature styling. The
problem is that DXF mixes different geometry types
(point,linestring,polygon,labels), while QGIS can only handle one geometry
type per layer.

There will be some work for better dxf handling in the upcoming months,
but for now, the recommended way is to use the dxf2shp plugin, FME, gdal
commandline - output to several other files, or other options.
