| Sep 30, 2020 at 22:58 | comment | added | mkennedy | You mentioned 1970. Is the data in Romania and you think they may be in Stereo 70? Try defining one as 3844 (Pulkovo 1942(58) / Stereo 70 instead. | |

| Sep 30, 2020 at 7:42 | comment | added | Michael Stimson | It sounds like a local datum which is common for mine sites, building plans and archaeological excavation areas. If it is a local datum and the site is fairly small the scaling of the features should be OK it's just the location that's out, you can generate a custom CRS with an adjusted false easting and northing gis.stackexchange.com/questions/203262/… should give some idea of your next step, you may need to affine the data if the scale/rotation is still wrong compared to known accurate data. | |

Welcome to GIS.SE. We need some more information. How were the .dxf created? If it was done using CAD and whoever drew this didn't bother to emulate a CRS and simply created the features around 0,0, you'll have to take it back to them and ask them to move the data to the correct place. Also, which CRS does QGIS initially assign to the .dxf? How exactly did you try to change it? Why are you guessing, which CRS the data is/should be in? Please edit your question accordingly.
