[postgis-users] DXF to Postgis using ogr

[Bob Pawley]

Hi Guglielmo

I found the QGIS dxf2shp plugin works with Dassault's DraftSight version of 
dxf.

One needs to run an unexploded version of dxf - once for polyline and again 
for polygon.

For text and accompanying points an exploded version of the dxf file needs 
to be selected.

I then use FWTools to import the shapefiles into Postgis.

QGIS is written in VC++ of which I am not acquainted.  Perhaps this will 
help you.

It would be of help to have a standalone version that imports all of the dxf 
information directly into Postgis with one click.

Hi Bob,
sorry for delay in answering.
Yes, Dxf2PostGis manage blocks like points and I don't plan (for the
moment) to develop extra code to do it in different way.
I'm not expert user of Org2org (I remember also a different name
"ogr2ogr") and I can't help you, sorry.
I can suggest you to explode blocks before use Dxf2PostGIS, if this is
compatible with your requirements.
In any case, good luck!
Please, tell me if you find a workaround to the trouble.
Guglielmo
