Hi Bernd
Yes, I receive CAD files all the time with it being 'georeferenced' but
actually they sometimes only include a grid overlay with coordinates and
nothing more. What I do and what I would suggest is importing the entire
CAD file into a Geopackage or File Geodatabase, then re-georeferencing
all layers/information within the file (I think you can do it using all
layers) concurrently to assign the correct coordinates and ensure that
the correct EPSG/ESRI CRS is assigned.
The other option is to request from the CAD guys a KMZ of the file,
which they seem to be able to output in the correct location, and rather
use this. You can then, if they have any attribute data embedded as a
description field, expand that using the KMZ plugin.
I hope this assists you.

So now I tried the import with EPSG 5653 and this one seems to work.
I am working now with geodata for around 15 years, but the CAD scene
never runs out of new obstacles for me.
What the f is EPSG 5653, and most importantly: Why is it it even being
used?
(Fun fact: once a CAD guy told me, after me complaining about his data
having just some local cartesian coordinates and no official CRS, that
his software would run much slower, the higher the coordinate numbers
were, so working with short local coordinates was his way to be able to
work at all.
Now these other guys just add another 2 digits? Obviously trying to
evade work!)
Did I already mention that I very much dislike CAD and its seemlingly
not existing philosophy behind it.
Thanks for the hints!

scramble the x-values by adding 33 before the otherwise correct
coordinates.
So EPSG:5650?
