Hi Jean-roc,
Thank you for your answer.
You're right but I didn't want to have to transform my initial dxf file in a shapefile.
Finally, using GRASS plugin in QGis, you can obtain a result which is quite similar to what I was looking for, without having to produce a shapefile, but having your dxf file in a projected coordinate system.
If someone is interested in,
Hope it could be useful for the other.

DXF doesn't support CSR but it does support projected coordinates.
Christophe > With QGIS 1.7 and gdal 1.8.0, you can save as dxf a .shp in
Lambert 1. WHen you open the resulting file in Autocad Map or DrafSight,
you can see that the coordinates used are the same.
If you want to work with several CRS you'll just have to make the extra
step of setting the correct CRS in Autocad Map and save as dwg.
