Andreas,

But QGIS reads DGN files directly, I assume through OGR, and with all geometry 
types in a single layer. We can then filter each geometry type and save to 
shapefile. Can't QGIS work the same way with DWG theoretically? If/when OGR 
provides a dwg driver that is similar to the dgn driver, then I would assume 
this would work.

Hi,

Currently, the dxf2shp plugin is more or less the only way to import dxf
data to QGIS, by converting the dxf to multiple shapefiles.

OGR (GDAL) recently included improvements for reading and writing in QGIS,
but because QGIS cannot read several geometry types from one single file,
it cannot be loaded directly from OGR without additional work in QGIS.

DWG is again a different beast. There is the opendwg library (that needs
to be licensed), and there are the attempts of other OS projects. However,
DWG is a complex format, and it changes with every new Autocad releases.
Not fun to write a reader/converter for.

It is therefore unlikely that QGIS will soon have DWG support. You should
ask the supplier of the file to deliver it in dxf or other more readable
formats.
