I agree with Marco and Jürgen. We should still keep the plugin. OGR is
getting a lot better for reading dxf, but QGIS is not ready to digest
it. And the dxf2shp plugins can split it up to the different geometry
types. QGIS, on the other hand just randomly picks the first geometry
type it hits, other types are not accessible with the current QGIS OGR
As Marco said, QGIS needs to be improved to properly handle dxf reading
through OGR, because OGR presents mixed geometries from a single source.
Also, QGIS needs to be able to properly handle OGR styling, OGR
labeling, block handling, etc.
My employer invested a couple thousand bucks on improving dxf reading
and writing in OGR, but now someone needs to come up with funding of the
QGIS part of the dxt reading/writing. The low level infrastructure in
OGR should more or less exist now.
