Answer to myself : CRS mismatch !
- The CRS of the source Autocad file is EPSG:3942; Autocad calls it : 
"*/Lambert 93 zone 1 CC42/*"
- In QGis, this CRS has a slightly different name : "*/RGF93v1 / CC42/*".
- The CRS of my QGis project is EPSG:2154; its name is "*RGF93v1 / 
Lambert 93*"

Then, I just made a confusion between the CRS names, and I didn't select 
the right CRS for import ;-)
